Full Metal Jacket
1st part (training) = 10/10
2nd part = 7/10
3rd part = 8/10
10+7+8=25
25/30=0.83333/1
8.3/10
4.15/5
So yeah, the start was actually brilliant, funny, entertaining, made you care about the characters, made you feel bad, made you shocked, just everything it was intending to do was just great.
However, the middle, while still decent, is a drop off compared to that, just pretty boring however the final part (the sniper sequence) is also very good.
