Last movie I saw Cruise in was War of the Worlds, right around the time he started really going crazy, saying psychiatry was fake, jumping on couches, and force lightning-ly Oprah (although that one was kind of cool lol). And I really only watched it because Spielberg directed it, otherwise I would've passed on it.
Oh wait, I saw him in Tropic Thunder, although I had no idea it was him til the end. But eh, he wasn't the star in that movie anyway, so it doesn't count
So yeah, I doubt I'll go see it, at best I'll netflix it when I run out of other movies to watch.
EDIT: And just because it's so dang funny, here's the clip where he uses force lightning on Oprah
