My vote goes with many of the others already cast: read it. I know I fail to appreciate the time investment that reading can be for some people, but one way or the other, you will be informed on your own terms. To me, that’s always well worth the investment of time, since I don’t care to rely solely on anyone’s judgment save my own [and my own’s flawed enough!]
I tried any number of classics early on and thoroughly disliked them. Then, for one reason or another, I went back and revisited several of them years later – and found, to my surprise, that I thoroughly enjoyed them. Your tastes and appreciation do change as life goes on and your schema broadens. Doesn’t really have anything to do with age, though, I think.
I’ve also been known to read books I suspected I would dislike, or even thoroughly disliked, for the same reason that on occasion, I’ll force myself to go read articles or literature put out by people or groups with points of view with which I disagree with strongly. It’s a good mind-stretching exercise, and I generally come away with it with some new perspective I didn’t have before. For that reason alone, I’d say finish CITR, even if you hate it.
Last but not least, I never agree with or say that any piece of literature is shit, dross or the like. I’ll agree that I may not like it, or that in my view, it’s overrated, or that, for whatever reason, it doesn’t do a darn thing for me. However, every work of art, literature or music speaks to someone on some level. It just may not speak to me in particular. Doesn’t make it bad. Secondly, if it’s published, that’s indicative of an effort that’s better than what 99.9% of the world can manage to do. [One of my pet peeves: people who boast that they could ‘whip out a book’ in some genre or the other in a weekend. I’ve always wanted to see those folks actually try it sometime – and get their weekend warrior effort published. Fat chance.] But in any event, the creator went to a notable effort, and I’ll respect that, if nothing else.
And incidentally, I thought R&J was almost as much a comedy of errors as a tragic love story. But that’s me. I still liked it, although Henry V remains my favorite of Will’s plays [thus far].
