LEGO The Hobbit is honestly amazing. It is such a step up from LOTR, with way more characters and a bigger map. Graphics are better too, but that is to be expected as it is newer. I don't understand what people are saying about the controls, but really, why would you be playing split screen with one keyboard? If you use two controllers the experience is almost flawless.
Some of the levels are admittedly a bit too long for my liking, especially the "Over Hill and Under Hill" level with the stone-giants, but that's because I never did like that part. Honestly, if you have the patience, then you'll enjoy every part of this game. Sometimes the quests require you to replay a level until you find a specific object, so they can be annoying, but as I previously mentioned, if you are patient then you'll have no issue.
