Just seen this and thought it was a pretty good edition to the series.
The CGI is now good enough for what is probably our first really in-depth look at the ape civilization following the fall of man.
Sure, it doesn't have as grandiose a story as Caesar's but it does a grand job of world building and showing us how the ape society of the distant future is functioning. The exploration of the mythology which has built up with regards to their past and Caesar's time is also interesting.
Proximus isn't even really a villain as such, which makes him and his vision for the future a nice counter to the uncertain goals of Noa's human companion.
Particularly enjoyed the ending, which, when you realise it is coming, you have to laugh as it has been set up throughout the movie.
And the little kicker was good too. Setting us up nicely for a sequel which may see this reboot series veer back towards it's origins.
Definitely well worth seeing if you're a fan of the reboot series...
