Bonnie + Clyde: Inaccurate, Immoral, Inane
Inaccurate: Warren Beatty and Faye Dunaway were made up to look like 60s fashion icons. They looked nothing like the real Bonnie and Clyde, who were both ugly little weasels. This was done purposely to glamorize their psychopathy and violence.
Immoral: See above - to glamorize psychopaths is by definition immoral.
Inane: I just put that in to be alliterative, but I think it's apt. This was really a dumb movie. Pretty but dumb. It showed no insight into the character's psyches.
