Main character can't act. I wasn't expecting cinematic excellence, but my goodness. Like most newer movies everything is so dark you can't make out things that happen on screen. There's a good bit of dark, mostly blurry stuff happening to or around the main character at multiple points in the flick. Writing/directing/starring was a mistake too, IMO.

I'm not a g*mer, so didn't realize the movie was based off a game until it was mentioned on screen. There has to be lore I do not know about, having not played whatever it is based on. I'm of mixed opinions here. Movies are made to be enjoyed by fans of something so it's ok to not spell it all neatly for those of us not steeped in the lore, but this was hard to get context from. WHY is the main character in a fucking homebrew apocalypse sub, like to what end is he aiming for, as well as the circumstances surrounding how he ended up in a submarine meant to sail the seas of blood. I have no problem w suspension of disbelief, but this was hard to do that for.

The last 45+ min were spent looking at my watch and trying to figure out how long I had left.
