There were a few excellent, high energy moments in 'Train to Busan' that really impressed me. Hoards of zombies in close counter environments chasing a likable lead child really made me sweat. These are some of the best zombie visuals I've seen with incredible make-up design. But the budget only stretches so far and most of the CGI looks dated for it's time. Not a huge issue but unfortunate that they couldn't reach full potential. Hoping to see that corrected in the 2020 sequel 'Peninsula.' I also didn't like the overtly evil "bad guy." Though the moments of badass heroism and the fight these humans wage for their lives make the experience worth it's admission.
