I had not realised it was only part one, so rather thought (like most in the cinema I felt) is that it?
I went with fairly low expectations having seen the previous attempt, but was a really surprised and pleased by the way it followed to the book which is complicated, to say the least.
I read a review which complained at the lack of imaginative sets and CGI action. If that's what you want head for Marvel. This is a superb rendition of a Si Fi classic.
