Premise - 14/20 - Love sports, not huge on basketball, so I was worried I wouldn't love it.
Cast/characters - 16/20 - Sandler's character was great, Hernangomez was very believable in the role, and most of the supporting characters did their jobs well. With so many NBA players in the cast, it was impressive that the egos were in check.
Plot - 17/20 - I didn't think I would love it, but I did. Believing in yourself and helping someone else believe in themselves was a good story, but the requirement that putting in the work is required to achieve your dreams was fantastic. The climax and the ending were well done.
Dialogue - 15/20 - The supportive conversation and the journey the two leads went on together was portrayed very well through dialogue.
World-building - 16/20 - I felt like I had a good look at the inner workings of the NBA combine and training programs here, which was a world only glossed over by most other basketball movies.

78/100 - 4/5 stars - A nice surprise from Sandler. He can play a wide variety of roles. If you're stuck because he spent too long doing Billy Madison-type movies, you're really missing out on what he can do.
