Wii u is great, much better than the Wii. The Lego undercover game is brilliant! Even for adults. The only thing that bugs me is the Wii u locks up now and then and you need to pull the power plug out to reset it!
The kids liked this game as they had seen the film. I thought the movie was poor and the game likewise. No where near as good as Lego City Undercover. Also the game crashes and locks up the wii quite often.
