I love De Niro, and he's been in a number of fantastic films, but he's made some very bad ones, too, such as Godsend, Showtime, 15 Minutes, The Adventures of Rocky & Bullwinkle, and Analyze That. And that's just this decade.

The last two I find kind of interesting, actually. They make me wonder, alongside better films like Meet the Parents, whether or not De Niro is trying to pull off some kind of Walkenesque transition to comedy, or even self-parody. Whatever the intention, the dude never seems to stop filming, and I think it occasionally shows in the quality of his filmography.
