I am at a loss to place this film, I'm not even sure if I enjoyed it or not, or if I could recommend it.
This is an action film with a ridiculous plot where some old guys have to go and beat up some other guys; but that really isn't important.
This isn't a 'serious' action movie like Die Hard or Transporter but it isn't a full send up like Black Dynamite or Gravy Train.
The production is strange. Normally when someone throws a grenade you get a slow motion sequence of the grenade in flight, followed by a close up of the villains face, then a few seconds of explosion. Here grenade leaves hand the next frame is bad guy blowing up.
There is lots of action, the fight scenes are fast and furious but aren't particularly well choreographed. Glover and Trejo deliver their cheesy lines and punch people adequately enough.
Don't take this too serious and you may enjoy. I did... I think.
