Ebert's review:
I don't get you guys. Ebert loved the movie. He has a few quibbles with it. But he starts out very clearly saying "This is the best of the three, redeems the earlier meandering, and certifies the "Ring" trilogy as a work of bold ambition at a time of cinematic timidity." ..."Still, Jackson's achievement cannot be denied. "Return of the King" is such a crowning achievement, such a visionary use of all the tools of special effects, such a pure spectacle, that it can be enjoyed even by those who have not seen the first two films"
Give the guy a break. He doesn't have to think it is the best movie ever seen by man to be able to say he liked the film...
