Others have said much of what I'm saying, but I thought I'd throw my hat in the wrong.
First, let me say that I liked the Harry Potter series. For what it was, it was a good series of books. I'm just more versed in Tolkien's works (been reading them longer), so I'm naturally going to come at this from the perspective of pointing out flaws in the comparison dealing with LOTR.
Second, let me just say that I don't think you can compare the two, beacuse the Potter series is based on ground LOTR helped to break, if not flat-out broke first. It's like asking which is better at running, the first horse ever to evolve or a horse that evolved to run? Of COURSE the later books are going to seem better--authors have worked very, very hard to make them so over the past 50 or 60 years.
3). The combination of "real-life" problems (growing up, first kiss, etc.) with the fantasy is done very skillfully in the "Potter" books, and naturally has absolutely no equivalent in LOTR. Similarly the relationship between magicians and non-magicians.
The problems in LOTR were real-life problems, just not MODERN real-life problems. This isn't Potter being better than LOTR, it's just a matter of setting.
4). The idea of a school for magic is pure genius, but, more to the point -- makes the increasing power of the magic as the stories evolve seem logical. In LOTR it is never really clear why the all-powerful Gandalf doesn't do much more much sooner.
This is simply wrong. The reason the "all-powerful" Gandalf (he wasn't, even later in the books) doesn't do much more much sooner is because he COULDN'T. Illuvator sent him back after he fell to the balrog. You're asking a character to shoot someone before he even has a gun in his hand.
7). Suspense is kept in a much more sophisticated way in the "Potter" books, especially in the richer secondary characters, whose "side" is sometimes not clear. The reasons for complicated characters' development (Snape, Hagrid, etc.) revealed gradually and make sense. In LOTR there is little chracter development at all.
Again, simply not true. I get the sense that you don't know what LOTR was trying to do, or what it was based on.
8). Comic relief done very well; Rowling has an excellent sense of balance between "serious" chapters and "funny" chapters (and how to tie them all together). Almost none exists in LOTR.
First, this is subjective. I found a few parts kinda funny (the whole "You breath so loudly we could have shot you in the dark" bit, the swan boats, things like that); obviously you didn't. Also, comic relief isn't necessary.
9). The characters mature believably also in the physical sense of entering adulthood, not just in having more powerful magic.
I'm sorry, but what does this have to do with LOTR? The characters in LOTR start off as adults. Well, by the time anything significant happens, anyway.
10). On the whole and in general, Rowling has a much better imagination than Tolkein. It's the easiest thing in the world to imagine an all-powerful lord of darkness whose eternal minions will overcome the world with all-powerful magic until the one hero saves them. But to imagine the numerous small details, the little daily magical spells, the annoying or funny magical creatures in a way Rowling does -- that fits into the story, however, that takes a lot more.
No. I'm sorry, but no. Tolkien is widely regarded as being remarkable specifically for his attention to details. If you look through the LOTR books you'd be hard-pressed to find any contradictions. Very few exist between The Hobbit and LOTR. And Rowling's backstory has none of the depth that Tolkien's did. Rowling made stuff up as she went along, and it's pretty obvious at times (in fact, Sluggy Freelance openly mocked the fact that it seemd Rowling added new wizard traditions for each book, which were never previously referenced). She tied it together pretty well, and I by no means am saying this is bad. I'm just saying that while she had better attention to detail for the characters, it was at the cost of her attention to detail for the world itself. And that illustrates why LOTR and Harry Potter are really incomperable works, at least in the way you're trying to compare them: they're completely different sub-genres, with completely different goals and must be judged by completely different standards.
Finally, I think it's telling that you're even doing this. You yourself have accepted that LOTR is the bar--that is the standard for greatness. Harry Potter, simply put, isn't. Not even in your own mind.
Skeptic said:
Creating entire worlds in fiction is quite easy.
While this may be true, creating interesting, consistent worlds is nearly impossible. Tolkien did it. The guy who wrote The Chronicles of Amber did it for the first five books. Douglas Adams more lampshaded this one. I'm sure there are others, but they're going to be a very small number. The point isn't that Tolkien created a world. It's that he did it well, in ways which Rowling hasn't. This isn't a bad thing on Rowling's part--she didn't NEED to.
Yes, reading the LOTR for the first time was a great experience for me -- I was 14. It truly created a "world of wonder". Reading it again in my 30s was a big disappointment -- not because I know the ending, but because the tropes which so fascinated me at 14 now seem to me rather childish.
I once read a review of The Maltese Falcon by someone who'd never seen it before. They were shocked at all the tropes and cliches in the movie. Until, that is, they realized that this was the movie that made them cliches--so many people were trying to make their move THIS movie without understanding what made the movie great that modern entertainment was awash in those attempts, long after the origine was nearly forgotten (seriously, how many kids even know what the movie is about?). It's similar with LOTR. Tolkien didn't write a trope-filled cliche of a book--he wrote the book that everyone else is copying, and its that copying that makes aspects of the book cliches. The book itself is the original (well, the introduction, anyway).
Anyone care to place bets on whether, in 50 years, we'll be talking about how Harry Potter is full of tropes and cliches? How many people do you think will base their works off Potter?
