It looks a bit...
Meh?
I guess I was expecting an unique storyline, rather than a tour of certain scenes from the shorts and film... To that level, it's slightly disappointing...
On the plus side, the scenes they have look exceptionally well done, and whilst have some staticness to a few of the characters, has a LOT more moving components than most (if not all) Merlin dark rides...
I'm sure it'll be a well-received ride...
