I probably smiled the first time I saw a movie which sent up 50s SciFi movies simply by exaggerating the bad parts of those movies (like the cheesy sets and monster costumes.) At this point, having seen dozens of such movies, it really takes a bit of extra cleverness or wittiness for me to be satisfied by them. Attack of the Moon Zombies has nothing resembling that until the credits, which is way too little and too late. If you've never seen one of these send ups before this might be a 5/10 for you. For the rest of us, 3/10. There is just nothing new here.
