Never seen 2 Broke Girls.
Most of the other stuff I've seen Dennings in I've liked her but her character in Thor just didn't work for me. Granted that Mjolnir is hard to say (let alone spell) it was buggy the way she kept calling it "Meow-Meow" like a little kid learning to say "apple" and then they're on the roof of the building and Jane is talking about the loss of her entire life's work
and Darcy is all, "I just lost my iPod, I just downloaded like 10 new songs on there."
Her character was just annoying in the movie.
