One of the real strong points of this film is that it perfectly balances the right amount of craftsmanship and attention to detail and at the same time not taking itself too seriously. The makeup effects aren't half-bad. Presumably they didn't really have to go all out with this, as though if they made the monsters real enough you'd find yourself having were-marsupial nightmares and considering the possibility that they might be around every corner. The idea is just silly. Yet they really made the things surprisingly detailed. There really is nothing like a trio of nuns with comically convincing Tasmanian tiger snouts.
In a nod to Troll 2's "Nilbog," the name of the were-marsupial town that Jerboa, the main character is from, is FLOW (Wolf, backwards).
This one really seems to have found the right formula for an entertaining and watchable humor/horror film. My only criticism was that it starts to drag a bit towards the end as though they had to make sure every little possible present and future problem for all the characters gets resolved. After the "ending" firefight, the movie goes on a little awkwardly for another 15 minutes or so showing the characters lives as they progressed through the next decade or so from there.
