There is a very fine line between uber-masculinity and for want of a better word mincing.

Predator stands on one side of the line and Commando is definitely on the otherside.

Rocky I and II and First Blood are on one side of the line, Rocky IV and Rambo are on the other.

Muscular men are not masculine in of themselves, Clint wasn't particularly muscular and Bob Mitchum got his amazing physique in Cape Fear by holding his gut in.

It's all about the attitude.

What made Life On Mars (the UK version) such a breath of fresh air for me was Gene Hunt was a flashback to an earlier time when men didn't need to preen themselves to fit in to a advertising executives idea of what a man should look like it was a self constructed and peer enforced masculine identity.

That said I think there is a need for films where supermen strut their stuff in as much as there is a need for films where wonderwomen strut their stuff but there needs to be a clever brain working the story and the audience has to be tuned into the inherent absurdity of the thing.
