Ignore the reviews for once. This is pretty much a rehash of the first film for a new generation. Great CGI, great fun and yes, there are plenty references to the first movie, the gear, the ghosts, the lot. Go see it, give the reviewers their cocoa and pack them off to bed with a copy of Battleship Potempkin, or if you're feeling mischievous, Battlefield Earth to know what a really bad film is.
