Few more thoughts after giving the 4K version a watch:
It looks better in 4K
Cloaked predator on fire looks awesome
Whilst the bear CGI looks good for the most part, the first shot we see it in looks a bit weird
Does a Comanche vs Predator movie need so many deadly animals? I think the bear on it's own would be fine, the mountain lion seems a bit unnecessary (though maybe it's integral to the plot?)
