Pretends at high action and intensity - and there are chunks of that - but heavily padded with backstory and family stories and buddy stories and war stories and group stories and etc. Lots of capital-A "Acting" where each person stares at the other for a minute or so then lets out a grunt.

And the action - when we get it - is often silly and cliched. A speeding car is T-boned by a truck. How many times have we seen that? Which btw is difficult to get right even as a stunt and impossible in real life. Machine gun battles in which the heroes are invulnerable, or heal in 15 minutes if they catch a few rounds.

Overall a decent plot worth about 1/5 of the time it all takes. Overweight, slow, and finally just... boring. Re-watch "24" instead.
