It's a surprisingly good movie. I felt the pacing was quite good, maybe a little quick. You don't really get to know the characters that well let alone the main character. Despite this you still care for her and the situation she gets into is well played out.
The dragon is well done and the flames are deadly. Liquid flame which bounces and flows through the chasms.
Unlike most modern films It's not too predictable and even if you know something's going to happen, the way it plays out is still a shock.
