Yeah, I think their theme music is pretty funny. That "sha na na na na na." I don't know if my interpretation of it is right or not, but it makes me think these same dudes were still living in the great days of the biker gangs of the 50's, trying hard to be something they weren't... most of them are about twenty years past their teenage years, so maybe they've just never grown up and have been this way all this time... still trying to get it right.
I think John Quade as the Black Widows leader, Chollo, is pretty funny. His annoyance with the inferiority of his gang might not get laughter out of me, but it does make me smile. And I love that at the end of the sequel he was smart enough to make this gang of losers "winners" for once.
The actors certainly seem to be enjoying themselves, I'm sure those were fun roles for them to play.
