Matt Hurt’s review published on Letterboxd :
The Predator is really just okay. At its best, it's a perfectly fine sci-fi action movie. The characters are cartoonishly over the top, but they function well together and have fun chemistry. The movie makes no sense whatsoever if you think about it too hard. The CG is really dodgy at times and it's clear the movie suffered from reshoots that don't really fit that cleanly.
However, my biggest complaint with The Predator is that it takes about an hour and change to really get moving. I feel like I'm in the minority here but the movie would have been much better if the stuff in the last 20 minutes made up the majority of the plot.
All said, it's really not that bad. It's a fun, throwaway late summer movie. But I expected a lot more out of Shane Black.
