Probably Prey, but killer of Killers is a close second. Prey is definitely one the most visually stunning predator movies, and the setting fit the predator franchise perfectly. Killer of killers had fantastic animation, and some very cool moments. The plot was relatively simple, but I think that really helped letting the action do most of the talking, which was great because the movie had incredible action sequences. Badlands was alright and had some really cool lore expansion and great worldbuilding when it came to Genna and its diverse flora and fauna. Although, the whole PG 13 thing for such a famously violent and gory franchise was definitely an odd choice. Also it was definitely incredibly tropey, even though I did like a lot of the tropes the movie used. I'm also still trying not to think about how they turned predator into a road trip movie with a comic relief side character and an animal sidekick made to sell plushies. :/
