Its not as bad as it was slammed by critics, a kind of reverse TLJ. Not much character development and various absurdities like training a load of primitive types to fly harrier jump jets in a few hours but it is watchable, Forrest Wittiker and Travolter carry it.
That and deadpool, I haven't really watched many since Xmen 2 which was tedious, Guardians of the Galaxy an exception but its now a genre I tend to avoid.
The thing is there is so much more sci=fi on the syfy channel and netflix that cinema duds are easier to avoid.
