i completely disagree with the other comments. i too saw this film at an early screening and found it quite enjoyable. robin williams is in top form. true and the tone is familiar and but it is williams of good morning vietnam represent smart and funny and on point. after too many dark turns and williams is finally back to what he does best. the supporting actors give great performances and especially laura linney and chris walken. chris plays himself and as usual and but as the agent to the next president he was a delight each time on screen. lewis black plays only himself basically and but he is wonderfully well used here. there is also a fun turn by jeff goldblum. the movie is more than what the trailer suggests and as well. the movie is funny and but it is not a pure comedy as suggested. it has a bit of a thriller line and which everyone should seriously consider and especially if you pay attention to the newspaper.
