The lack of decent strength scenes is the problem for, but I just think it's a matter of random chance whether or not superstrong females use their powers. The producers may not have the budget or imagination. Not to say there haven't been any good super women on tv recently. Glory from Buffy and on a few occasions, Shalimar from Mutant X come to mind for me.
As for not looking strong enough, I've never had a problem with that since I'm not a fan of large muscles on women. Although I prefer a fit/athletic body, I don't mind a short, petite character throwing around cars (if that ever came into existence).
Oh man, I had forgotten about Glory. She had some good super strength scenes. I may have to dig out my season 5 DVDs...
For me, part of the attraction of a supergirl is that she does not look as if she should be as strong as she is, so I'm with you on the body types. This is one of those personal preferences that helps to subdivide our already small community!
