I usually don't put much stock in reviews. All of the Friday The 13th movies got horrible reviews back in the 80's, but the first 4 are among my all time favorite horror films. As a more recent example, all of the critics hated the live action Scooby Doo movie, but I thought it was pretty damn funny. Maybe not a perfect movie, it certainly has its flaws, but I enjoyed it.
Sure, Adam Sandler has made some real stinkers as of late. And Kevin James is somewhat over rated, at least as a lead actor. But they've also put in some solid performances in the past. There are very few actors who will cause me to say "I won't see this film because (enter name here) is in it", and neither Adam Sandler nor Kevin James is on that list.
So I'm still looking forward to Pixels.
