I've always enjoyed it for what it was; A campy, goofy movie based on a video game. It never took itself too seriously, and it just kind of accepted itself. Just watched Borderlands, for example, and it was horrible and flat. The characters were there, but they weren't the characters, just 2D imaginings of them. Anyway, looking up reviews, I found a great one that compared it to the '93 SMB. They said that we needed another SMB, and we didn't get it, Borderlands wasn't "interestingly stupid". That's a great term. Interestingly Stupid is definitely what SMB was, simultaneously a blast, while also being the dumbest thing you ever saw, and you can never quite put your finger on the reason it(kinda) worked.
