Well when I think LARP I see this!
I vaguely remember a few years ago a film called Knights of Badassdom was being touted during Comicon coverage. Well then nothing came of it. Well low and behold what do I see on the Netflix, but this very movie. Well since it seemed to not get a theatrical it must have had a giant hiccup somewhere or just be bad.

I knew straight away I had to watch this!
Alright. Here we go!
Knights of Badassdom follows three buddies: Joe, Eric and Hung. Now they all live together and we get that they used to play D&D together. Now one guy moved on but the other two delved deeper and are now LARP’ers (for the few people outside the nerd world that is Live Action Role Playing where you act out role playing games instead of just playing them on the table). We see Joe get dumped and he is kidnapped by the other two and taken to some big LARP event. There he is coerced into playing along. Why? Well he sees a girl named Gwen and wants to get him some of that. Along the way Eric tries to level up his character by doing a ritual spell. However he just happens to be using a creepy old book he won on Ebay, that low an behold does what? Summons an actual demon. It gets better, see the demon takes the form of Joe’s previous girlfriend. Now the LARP’ers have to face down a creature from beyond with nothing but foam swords.
This was anything but bad ass. It was a damn horrible mess!
