"Eclipse" was all right, not too different from the first two films as far as I can remember. I only vaguely remember the books, having read them more than year ago. But at least I read them before seeing the movies. The first had already finished its theatrical run when I began reading the books. I then saw the movie on DVD last summer.
I'm not that great at writing movie reviews, incidentally. I attempted this a few times on IMDB.com and Netflix, but no one has ever found any of mine helpful.
