Values Dissonance: Critter becoming a draft dodger for the Vietnam War is treated (at least by himself) as being an unforgivable act which will put him on the FBI's Most Wanted list. Although the draft was unpopular, the movie was filmed in 1968, when draft dodgers were prosecuted if discovered. Eventually President Gerald Ford offered conditional amnesty to persons who had dodged the draft, with President Jimmy Carter giving an unconditional pardon to all draft dodgers in 1977. This makes Critter's treatment of draft-dodging as such a horrible crime seem a little strange from a modern perspective.
Even then Critter is playing it up a bit much. The Most Wanted list is Exactly What It Says on the Tin: a list of international terrorists, serial killers, kiddy porn producers, and other people horrible enough to be considered the Most Wanted criminals. If draft dodging was all it took to be lumped in with that crowd the Ten Most Wanted would be more like the Ten Thousand Most Wanted.
Michelle seems more disgusted that Critter is a draft dodger than the fact that her boss is a sleazy violent mobbed-up drug dealer who has already gotten her to smoke pot and is showing signs of wanting to pimp her out (go meet customers, go to parties, etc).
While Harry was stupid, Buz was an even bigger moron for actually killing him, or at least doing it right that second, not to mention leaving the fingerprint-covered murder weapon behind at the scene. It's probably safe to say Buz is doing a LOT of time in prison right now.
Mike (as Buz): Yes, my plan is perfect. I've been spotted by several people and I killed a guy! Tom: Well what do you expect? He's only a child!
Critter also shows quite a bit of stupid for confronting known mob boss Leo and telling him that he's leaving and taking Leo's new prize dancer with him... and doing this totally unarmed. Then again, he was tough enough to disarm and beat down Leo, Buz, and another of Leo's thugs by himself.
