This is mean but I kept comparing the Dan and Blair scene to Chuck and Blair scenes and thinking they just aren't as good. Ed and Leighton are so good at angsty drama. They own it. Penn and Leighton are good actors but for me they just don't compare as an acting couple. The chemistry difference is so big. It's like a tasty hamburger and filet mignon. Hah
Other than finding DB really underwhelming I'd say my other biggest impression was that the show itself felt weird and kind of shallow. Some of the scenes with Serena, Nate and Chuck in LA were alot of fun but in general the show felt off to me.
