I just finished watching the first episode of the new series and was pleasantly surprised - the writing was better, the production values seem to have gone up, the film style looks better (more filmic, less BBC) and Matt Smith was very good. Also, the chick who plays Amy Pond is quite hot :)
I lost interest in Dr Who but I might start watching it regularly again now. Hopefully it won't turn shite again (Tennant was the Pierce Brosnan of Doctors - good Doctor, crap plots and scripts).
