I just watched this animated movie. I think it's part of DC's superhero movie releases (the previous one was the Wonder Woman movie.)
It's based on the events around Superman/Batman 5-7 approximately, with Luthor becoming president and a large Kryptonite meteor threatening to crash into earth.
Power Girl is in the movie, but there are basically no notable scenes with her of any type. They do do justice to her uh, cleavage window though.
Yeah, there were no great feats, but damn there were a lot of superwomen in this cartoon. including a good (failed) stomp fro giganta, one of my favorites
"If you threaten our son again, I'll put my heel through your skull"
I liked the Power Girl look in this movie (very sexy) but the character was really weak. Not anywhere near as strong (both personality and physically) as she is in the books.
