I saw the movie yesterday and from a critical standpoint, this movie is nothing special. The jokes are predictable, the plot is simple, and the visuals are nothing to write home about.
All this being said, it's fun. It's full of references for old fans of the game franchise, the cast of characters is large, and easily recognizable, and for an $11 dollar movie ticket to see it in the 2D format it's worth the cost of admission. Chris Pratts performance as Mario is inoffensive and average, as is that of Peach, who comes across as more of a Princess Daisy then herself. The rest of the cast do better jobs in their roles, with the stand out performance being that of Bowser voiced by Jack Black.
It's a middle of the road production that sadly does not live up to hype, but if you take it for what it is, it's an enjoyable time.
