Cockneys vs. Zombies is actually pretty good. I'm not sure it's one I need to own but it's not bad.
I watched all 4 movies in the 4-Action Packed Movie Marathon in about a 14 hour period between Tuesday and Wednesday. Loved Cyclone and Eye of the Tiger. Not a big fan of Alienator or Exterminator 2 but I enjoyed them to an extent. I've reviewed them for my site
if anyone is interested. Not my best written review (doing all 4 at once was a bad idea) but hey, there are lots of pretty screenshots
