Ah the cheese, the cheese.....
I'm sorry but I thought that clip was embarrassing, it was a spiritual cousin to the production of the old Power Rangers series.... I wish they wouldn't do that it just gives the impression that Doctor Who is cheap... just announce who the actress is, what's the need for the tacky pomp when announcing cast members.. self importance at its worst..
I don't think we can judge to soon on the companion, this really isn't a great indicator as to what the series will be like, as even Capaldi came across bad in this clip, but first impression was that she didn't impress me or make me look forward to her, but like I said I think we should give her the benefit of doubt.. her first episode will be the real test....
I really think this clip was a bad idea though, IMO, at-least it was for me, I would of been more excited just to hear who was cast rather than have some dodgy lame thrown together skit as a way to introduce the new companion, its a bad choice for a first introduction.
