Oh I have so many favorite movies, it would be hard to list them all. It might be easier to name directors and actors. I'm a huge Kevin Smith fan, love Rob Zombie, huge fan of Brad Pitt, Dustin Hoffman, Sean Penn, Michael Douglas...the list is very long.
Most hated movie...? Would have to be...The Ice Cream Man. It was just beyond bad. BATS was pretty horrible, too.
