(SPOILER FREE REVIEW)
Here's the best thing I can use to describe this film. Picture this. You're about to have some nice tasty pancakes for breakfast, and you get some sweet sweet maple syrup to pour on the pancakes and you watch the syrup drip and drop and your mouth waters all the more. You grab your fork and knife and cut a small slice, then scoop up it into your mouth and you taste mashed potatoes and gravy.
This movie is essentially exactly that. Now there's nothing wrong with mashed potatoes and gravy, in fact they're actually really good. But you were expecting pancakes and maple syrup, so you go "whuhah?" and scrunch your face a bit. This movie had a good idea, and concept, and they made a pot of mashed potatoes look like pancakes because they hadn't ever made mashed potatoes before but had plenty of experience with pancakes.
Guys, if you're making a movie that's a new idea, explore that new idea! Don't fill it with cliches, I could see 90% of the things coming from a mile away because they're so generic in a movie that had some potential to be really good.
Overall, I rate this a good raman soup out of a juicy steak cooked with sea salt on a BBQ. It's good, but it's a cheap meal that was processed through the same process a lot of movies go through and is pretty much the same as other movies even though it says "NEW FLAVOUR" on the packaging.
