Finally got round to watching it, it sucked...
Other than McKenna and possibly Williams, I didn't give a shit about any of the characters and wasn't even remotely bothered when they were killed off.
The CGI was SyFy Channel level at times.
The action scenes were instantly forgettable, including the utterly anticlimactic final showdown.
Whoever came up with the "friendly Predator dog" idea probably shouldn't be allowed to work in the business anymore.
How many callbacks to lines from previous films do we really need? Thought I was watching a parody at times.
The "Predator Killer" scene at the end? Garbage.
Honestly, I'm struggling to remember another film which had less of an impact on me than this one...
