If you're in for the friendship and youth vibes, go for it. If you're in for the mystery, then I suggest you look elsewhere.
I came for both...more for the mystery. I was disappointed... but not entirely... I found the mystery part flat and the explanation lazy and lacking... yet, the refreshing friendship and bonding moments ALMOST made up for it... and the music and some cinematography were a great bonus.
The acting was good overall, not bad and not exceptional. The main actors were well cast and they did a good job portraying their roles. The rest of the cast also did a good job supporting them.
At the end, as long as I didn't think about the cringy mystery part, the movie left me with a good feel. I don't regret watching it but I wouldn't watch again.
