Good story, but I think it was broken up by telling folk who the characters were. Not really avoidable in the first episode after such a long break.
Incidental music got a bit annoying.
Mum thought it was great they used the wheel as she tought they were going to blow it up! :-))
BTW, one thing I think I've seen before is a box swallowing a person then going 'Burp!'. I wonder where that could have been? :-)
Will reserve final judgement until after next weeks show, as that should have less backstory to cover.
