And for a "feature-length" episode is remarkably unambitious, blowing it's budget in the first five minutes and then being mostly people standing or sitting around talking. (With more than a few scenes that pretty much repeat what's already been covered by earlier scenes.) Do they not have a Script Editor any more?
When I read the script, I could see why it was "feature-length." It's "feature-length" because it's a two-parter without a cliffhanger in the middle. Virtually nothing happens for the first fifty pages or so. It's overwritten and totally lacking in subtlety. With a solid edit and rewrite, it could have been brought down to the 50- to 60-minute range quite easily and been stronger for it. As it stands, at least as a script, I think it's likely to be one of the series' weakest Doctor intros.
