I see there are a LOT of reviews of Bullet Train here, so I will be brief. I usually only watch action movies if they contain a large element of humor and, if possible, an actor I like. So I gave Bullet Train a try. I figured Brad Pitt wouldn’t get involved with a totally awful film.
So yes, it was humorous and often entertaining, with the comic book violence action films often seem to include, I guess because the audience demands it. I almost gave up on it halfway through, not because it was boring but just because the story seemed so shallow and the subplots didn’t grab me. But the film’s action moved along fast enough for me to stick with it. Like I said, it is entertaining in places and witty overall, though I can’t imagine ever watching it a second time.
