I hope and trust everyone had a good holiday weekend. I watched this on Saturday, it was indeed a mashup of Groundhog Day and Starship Troopers, but a pretty good one. These are the more infrequent fancier aliens, the more typical ones are basically tumbleweeds made up of whipping mechanical tentacles. Vaguely neat, but again not the sort of thing that kids will fall in love with. Monsters can be just too non-human or non-animal now for their own good. You can make good ones, like the Attack the Block beasties, but they are definitely rarer.
