Some more recent ones that maybe are too new to say but seem to fit in this category:
Batman Begins
Spider-man 2
Pirates Of The Carribean

Most are films that were succesful (or at least, made decent money) at the box office while being heavily praised by the critical community.

That said, there will be no film that is universally praised. For one, there's always someone who wants to be the dude who hates the movie everyone loves. Several people here take pleasure in being THAT dude. If we all love City of God, it's pretenious. If we love Batman Begins, it's boring. Etc.
