For me, I think Bullet Train made every of my expectations and more. I never for once was hoping for a movie with some important life lessons or whatever. I knew it was going to be an action movie and it was it.
The twists on it was something else. When I found out all of the assassins were there (except for ladybug) simply because the white deaths wanted them there, I was mind blown.
One thing I didn't like was the comedy part (or whatever they felt that was) by Channing Tatum. It was so unnecessary and wasn't even funny. Aside from that, everything else (the action and the twists) was topnotch.
You are on point as usual prayzz. And also on point about the twists. All in all, its something we can watch with friends on a lazy afternoon.
