I put aside the fact that we are used to big Hollywood movies with big budgets for special effects and acting coaches. I then asked myself if the core of this movie, the the overall story, was it any good? Was it entertaining? Yes, it was very good, it held my attention, I was invested in the characters and the outcome of the story. It's NOT a big budget film, don't let the lack special effects keep you from enjoying the story.
If there was a way to give it 4.5 stars I would have only because there were two scenes that seemed a bit clunky, but those were just tiny flaws when keeping everything else in context. Watch the film, you will enjoy it.
It's a good movie for the whole family to watch together.
