Knights of Badassery
I had much higher hopes for this movie. I expected a comedy which poked fun at geeks, RPGs, and LARPs, while having a horror theme running through it. Instead, it was all over the map, comedy, romance, drama, spun around a slasher movie which ends with a really cheesy resolution.
Addition: Dinklage's part is, not surprisingly, less central than is implied in the trailers. His screen time is less than I'd hoped for, and there are some character threads for him which are abandoned (as there are for each character). Side note: It's hard to write each of these criticisms without using the word "short"; "cut short," "falls short," "given short shrift," etc.
I know there's a lead-in for the cheesy-but-largely-played-straight finale, but it really surprised me that the big resolve involved straying from LARP/RPG elements and a callback to an earlier, one-off scene played for laughs.
