don't bother bringing your kid to watch the 12A version of LEO, the plot won't make sense and it'll just waste your time and money. i know this may upset alot of kids who do want to see it regardless of how many cuts there are, but it won't add up at all. i'd recommend either seeing the uncut (18) or 15 version.
right, so, regarding how much hype this movie has gotten, it's sort of worth watching. i wouldn't say it's completely worth watching it as the plot really doesn't add up since i really don't understand what i had just seen. there wasn't as much gore or blood, but most certainly unsuitable for children under 15 or those who dislike blood and minor gore. honestly though i'd much rather rewatch master than leo if i had to choose + the songs were the only things that carried this movie, otherwise it wasn't that great in my opinion.
overall, i give LEO a 6.5-7/10.
