I avoided the obvious underrated and overrated like Julia Roberts, Don Cheadle, William H. Macy, Paul Giamatti, Halle Berry etc
5. Jack Nicholson - overrated - urgh, can we have the 1970s Jack back please?
4. Maggie Gyllenhaal - Underrated. See: Sherrybaby, Secretary and just about everything else. Her brother gets all the attention, hopefully that will change.
3. Tom Cruise - underrated. Yes that right, underrated. Sure in real life he's crazy, but most people think he's overrated but I've yet to see a film in which he doesn't draw me in. Sure there is a few films I don't like, and I don't expect he'll ever be Marlon Brando II but what the hell, I like him.
2. Parker Posey - underrated - I have an unhealthy desire for Parker. I love her in absolute everything, from Dazed & Confused to Oh in Ohio through Personal Velocity and, obviously, her scene stealing performance in Superman Returns.
1. Tom Hanks - overated - quite possibly the most overrated man alive. He's likeable in comedic parts, but I just don't see why people make out that he's a really good actor. I just don't get it.
Honourable mention to Brad Pitt as underrated, I would've had him on the list but I think people are starting to realise how good he can be.
