“Bullet Train Down” (*1/2 out of four) was an ungainly action thriller about various travelers (Tom Sizemore, Rashod Freelove, Caroline Vargas, and others) aboard the fastest train in the world in Osaka but suddenly find out that the train is equipped with a massive bomb that will go off if the train dips below 200 MPH! The kind of cheesy substitute that’s made by low-budget filmmakers to cash in on a more expensive popular one (last years “Bullet Train” if you couldn’t guess) but it’s actually billed as a remake of 1975’s “Bullet Train” and rips off more-than-a-little of “Speed.” Either way, it’s forgettable and dumb. Sizemore looks groggy and hungover as usual.
