Mind, my friends and I saw the movie based off it's title alone. It's cute, though obvious in it's plot and direction-- you know where the movie is going within the first five minutes. My main contention with the plot is that while it remains tolerably consistent, they never explain a lot of the things behind the characters. An alcoholic father, overworked mother, stressed-out sister... that's a bad family, but aside from the occasional mention from the sister, there's not any resolution. I was also confused as to the scene with the bottles... it seemed pretty random.
The writing is a secondary concern... the kids weren't bad actors, but their script left a lot to be desired. Unfortunately, what could have been a cute niche movie was pushed aside for a single, blah special effect, lame scripting, and a glaringly obvious plot.
