CinemaSins is usually able to cram its "everything wrong" lists into 15 minutes or less, with a certain Transformers movie being a notable exception with not one, but two 16-minute clips. While the channel's take on Adam Sandler's Pixels doesn't reach these lofty heights, it pushes the upper limits at a chunky 20 minutes.
I'm going to take a guess and say more than a few people reading this have yet to see the film -- me included. This video certainly won't compel you to do so and if you're even considering a viewing, this is the only tonic you need.
Maybe, just maybe, it'll be good fodder for a bad movie marathon, but even then you'd just be left annoyed at all the missed opportunities and potential.
