I'm a fan of the Lego games, and snapped this up on day 1. As with all the Lego games, it was fun, a bit silly in places and generally a good way to spend the time. Unfortunately this was marred a little by some graphical and model glitches - particularly annoying where a character gets stuck unable to extricate himself. There's always a way out - switch players and use a 'travel point' to jump to another location on the map - but you shouldn't have to.
Having now completed the main story arc, another annoyance has revealed itself. Among the quests on the map are 'personal' flying races - where you use a flying character to nagivate through rings with a (fairly tight) time limit. I've found the flight controls, combined with the fact that characters automatically land when close to the ground, to be frustrating.
All in all - A fun game, but not quite up to the high standards of Lego Harry Potter, Lord of the Rings, or the Batman games. I'm not going to be religiously trying to 100% this one.
