I like and respect all of the actors, but the plot was just horrible. in the 1st movie, the main guy's brother is killed and he's framed for it.
here, they took revenge for this guy that "raised" the ml, but so brutally and just to teach him go.... I mean, it is a traditional game, but if you switch it to chess, it'd still be as pointless. sure they played several Saw like Go games, but everything happened just for the sake of the plot.
it's like, if it was a sport like karate or taekwondo, it'd have some action and suspense, beside the whole backstory of the sister felt like a cheap move to add to the "revenge"

Loner had a more solid reason for revenge, his dad was murdered and he got severely hurt by evil guy that raised the ml... but his story was just used as a time filler..
it's funny how a 1 hour 45min movie felt like a 5 hour one.. also this is the type of movies I hate, they add creepy and gore as a way to be edgy but it just looks silly

the acting was great of course, and I never rewatch things
