There's a lot of great ideas that develop the plot line. A lot of effort and money clearly went into cgi and effects.
It was very sad to see how badly some of the characters were writen while others had a full circle like Dieter closing the safe again and Kate
Ultimately a lot of the plot point were predictable. Characters always seemed to have time to chat-chat while they only had minutes to live. It was annoying.
I enjoyed the ending, but I'm not going to watch it again.
