I want you to take a good look at the picture above.  Upon first glance, it looks kinda cute, right?  Shorty, super-deformed versions of classic Marvel heroes are absolutely adorable.  Who can help but smile at the sweet lil' Silver Surfer?  Cap is cute too, and even Wolverine looks positively huggable.  Now, count the number of fingers they have.  WHOA!  They have three fingers and a thumb!  That's a bit disturbing.  This swing of emotion, from the initial "awww how sweet!" to the eventual "Oh gross, that's abominable!" exactly describes the feelings I had while playing Marvel Super Hero Squad.
