Some stupid things about this movie - spoilers -
-How could she be stupid enough to date the cop investigating the murder?
That seemed pretty naive.
-It was smart that they thought of telling Claire that they changed the furniture in the apartment (at the end) BUT... how did they know for certain that she was going to drive out, get the gun and then come back to that apartment and plant the gun! And why, after seeing Mary outside of the apartment, would Claire still go into the apartment - when it would be obvious that she was doing something suspicious there!! That had to be the stupidest thing about this movie.
-And also, as someone else said - what exactly was her motive for killing her lover?
-And finally... If Warren got beaten up by Barney the first time, then why is it that when he went to his apartment to kill him, even after putting the pitchfork thing down, he was man enough to challenge him to a fight - AND BARNEY BACKED DOWN! That doesn't seem consistent at all.
haha
Otherwise - it wasn't a bad movie. I liked Warren.
