The Bunker is an interactive movie, but with very limited gameplay and very frustrating QTEs. I blocked at the last QTE, just before the choice that decides the ending. Despite this, I still appreciated The Bunker, but I had to accept from the beginning that it's a movie first and a video game second. The acting seems "cold and stiff" at times. At least that's my impression.
So...
* If you like a movie and the low gameplay + hard QTEs don't scare you, get The Bunker.
* If you want a narrative game with lots of choice and gameplay, skip it, you'll get bored.
