I won't say whether or not this movie is better than the Hunger Games (IMO it is much better xD), but Battle Royale has an epic air to it. It's filled with humor and irony and yet it still conveys a serious tone. Definite 10/10.
I enjoyed this movie, although at times it seems like the filmmakers were themselves unsure of the film's orientation - a campy, tongue-in-cheek comedy, or a more sincere message of acceptance. Ultimately I found it good, but not particularly memorable.
LGBTQ kids growing up in hostile environments might find the movie helpful, though - it's uplifting while also delivering a good dose of laughs along the way (or was it the other way around?...).
