The thing that was most annoying about the first or second of Sex and the City — characters breaking the fourth wall and talking directly to the camera — is actually one of the only things that makes Showtime's Secret Diary of a Call Girl watchable for me. Maybe it's because the source material is a blog, and the most appealing aspect of hearing these trick stories is getting the straightforward perspective of the woman involved. Or maybe it's because I find Billie Piper and her accent incredibly charming. Whatever the case, last night's episode, the second so far, didn't suck — much like Belle herself, who ditched out on a client in the middle of a sex party. Clip above.
