Pretty much my thoughts as well. I'd give it a B-. It wasn't great, but it was good enough for me to keep watching. Aside from the dialogue and some of the editing I felt like they tried to pack too much in too soon. I don't think we needed to be introduced to so many characters in the first ep. Also, Selina's physical presence was a bit too self consciously "cat-like." We get it, she'll become Catwoman, trust the audience a little bit, you don't need to beat us over the head with it.
On the plus side I really liked Jada Pinkett Smith. All of Fish Mooney's scenes were great.
All in all it's just the pilot. They'll have plenty of opportunity for improvement.
