Hell, I'm surprised that CinemaSins managed to get their assessment of Indiana Jones and the Kingdom of the Crystal Skull in under 20. I figured they'd need to spend at least six minutes on Shia LeBoeuf turning into the King of the Monkeys alone.
As a huge Indiana Jones fan...I actually have no problems with Temple of the Crystal Skull. It is exactly as good and as bad as Temple of Doom. One has Shia Lebeouf, the other has Willie and Short Round. One has Aliens, the other has a pretty innacurate and slightly offensive portrayal of Kali. One a hiding in a fridge to survive a nuke, the other has surving a fall from the plains over the mountains of the Nepal in a inflatable raft. Both are equally inferior to the two other Indy movies. But since they are still Indy movie and Harisson Ford is still pretty damn good with the role, i don't care, and I watch them anyway.
You don't like it? Then just don't buy it, watch the other 3 only, and stop whining
