I preordered the steelbook box set that's exclusive to Wal-Mart, it was a very good movie. Just another case of "ignore what the critics said and see it for yourself". The voice acting imo was a bit spotty, some sound better than others.
Seth Rogen basically put no effort into making a unique voice and you can easily tell it's him lol. Chris Pratt was alright, not bad, not great, just alright. I think Jack Black stole the show though as Bowser.
I did like the bit of Nintendo references sprinkled throughout too, a Twitter post showed a bunch of references in one shot showing a picture of Glass Joe from Punch Out, an NES system in front of the Mario Bros.' TV, and one of the ducks from Duck Hunt was in a painting. I hope we get more promising animated adaptations like this in the future.
