I thought It's a Trap was pretty decent with some genuinely funny moments but quite a few groaners as well.
The presence of American Dad and Cleveland Show characters seemed a bit unnecessary, since there are still Family Guy characters that haven't been used, Seamus the wooden-limbed sailor for one. However, I can't really think of anyone other than Tim the Bear who could be Ewoks, so I'll let that one pass.
There seemed to be more of the standard Family Guy cutaway gags in this one than there were in the New Hope and Empire parodies.
I was satisfied anyway. Family Guy doesn't satisfy me too much these days.
