First episode I wasn't sold on Whittaker either.
Again, no I hate female rant. I went in with an open mind, but somehow I just didn't feel her. The bit where she confronted the villain in the end fell flat. The first episode in a new Doctor's run usually involve him finally getting himself together in time to confront and banish the episode villain. When Matt Smith did that, it was brilliant. And David Tennant's sword-fight bit was memorable. Somehow, I didn't feel it with Jodie. I don't know whether it was the script, or a lack of gravitas in that sort of scene. But it felt out of place. Her going; "You're a cheat", didn't feel like she was insulting him. It sounded like a child complaining that they'd lost a game of Snakes & Ladders. Even the bit where she jumped between structures played on the screen like it was some big defining moment. But I was just sat there; "Oh look. She jumped." I didn't feel The Doctor was in any danger, and thusly wasn't particularly blown away by it.
I'm not necessarily blaming that all on Jodie. Maybe it was something about the script. When The Doctor came out of the charity shop, and she was in her own custome, it was the first time I felt; "There's The Doctor." Combine that with the fact she got rave reviews, I decided to reserve total judgement until I'd seen two or three episodes and was more used to her.
Second episode, I enjoyed more. Wasn't the most action packed of episodes. But on complaining that I didn't like her confrontations the previous episode, maybe that wasn't a bad thing. The three companions suddenly seemed like a good idea. Jodie pulled them together more. The scene with Ryan running out with the gun, then running back, you felt it was a confrontation that The Doctor "won", without it being the same way previous Doctor's would've dealt with the problem. Also later encouraging him to get up the ladder, despite his condition was done well. She seemed more of a team leader in this episode.
