We watched it over the weekend, and thoroughly enjoyed it.
It's not a new story by any stretch........many many odd couple Huck Finn (which they even reference) coming of age/adventure movies have come before Peanut Butter Falcon.
But in an age of can't go two weeks without another super hero movie or reboot/sequel no one asked for, I gravitate towards movies like Peanut Butter Falcon. Movies that have so much heart and soul that you have to be dead inside to not enjoy.
So I also highly recommend this movie. Especially this time of year when families are all home for the holidays and looking for something to watch everyone can enjoy. This movie definitely fits the bill.
