Bad watch, probably won't watch again, and can't recommend.
As much as I thought I would enjoy getting in the way back machine to see Christopher Lloyd getting up to whacky antics, this was disappointing.
It's a bunch of rich, spoiled kids tricking their parents into paying for what they is a way to get rid of their kids for the summer, and the kids basically creating a criminal ring to facilitate it.
I see a lot similarities between this and "Accepted", but where "Accepted" was built with better intentions by the characters who were adults that ended up dealing with a situation and turning it to be an attempt at betterment, "Camp Nowhere" grew the conspirators first and then committed to a fake camp.
This movie just doesn't have the fun charm that its future counterpart has, and that can probably be attributed to the child actors involved. They're not all so bad, but they're mostly typical child actors.
Sure there are some fun moments in this, but the overall story is severely lacking, and we don't need a fable to tell that this kid is going to be sorry and that he was wrong at the end of it.
