I used up all my suspension of disbelief on the assumption that dragons:
- are real,
- are basically huge flying kitty cats who breathe fire,
- are also video-game entities with a "shot limit" and armor stats, and
- hunt in a species-heterogeneous pack.
I'll believe all that stuff about dragons because I don't know any facts about dragons -- although their psychology toward the end seemed entirely unlikely given their social structure -- but I know some facts about languages, and that movie made NO SENSE to me.
The female character with the most lines is a strong young woman named Astrid, and while her character development had promise at the beginning, she soon became The Love Interest with The Recurring Line. Oh, I appreciate the fanservice, and I'll happily read any rule-34 fiction including the line "this is for everything else", but I'm more appreciative of the earlier Astrid: an ass-kicking chick who hasn't been dressed up all skanky or drawn with scoliosis-inducing tits AND who has interests other than boys -- namely, being the best warrior in her class.
I got in for free because Regal Cinemas admits the companion of a wheelchair-using person at no charge, and the price was just about right. Maybe a little high, but not by much.
