Like you I saw a bunch of commercials for this show, most bugged me, especially using that horrid LMFAO song, but when I tuned in it was actually not that bad.
With shows like Entourage, and most recently Matt LeBlanc on Episodes, the idea of celebrities playing an exaggerated version of themselves has grown tired. James Van Der Beek was not terrible, but not nearly on the level of LeBlanc on his Showtime series. If they use him more like Tracy Morga on 30 Rock it would be much more effective.
Dreama Walker is June, a poor man's Joanna Garcia, but I give her credit for being much more likable than the majority of ABC's female comedy leads. Her character is a bit too straight-forward, but she can be the more serious half of the two and be funny at the same time if the writing improves.
Krysten Ritter plays the title character, and while she is very high energy, the majority of her delivery is a bit slow and not funny. She has been on Breaking Bad, Til Death and Gravity, she has some TV credits, but needs to be better especially since she is expected to carry the show.
Those three stars were fine, but the rest of the cast is downright terrible.
I went into this show expecting nothing, but what I got was a pilot that was really not that bad. Not funny, but I grew interested in these characters and I am curious where things go from here. It is a little bit different than most shows on TV and for that reason I hope it succeeds.
