I'd heard someone said this is the best of all the Kendrick Brothers' movies so far. Went to see it last weekend with my son, a friend and her grandson. It was AMAZING and I 100% agree about it being the best.
Of course not everyone will feel that way but IMHO it's definitely worth going to the theater to see it and to support it. But fair warning - take tissues. My son who is 12 and isn't a crier like mama at movies even said it got him at one point.
