On 1st viewing I hated it!
Didn't help that on the UK poster there were loads of attack choppers taking on hordes of scary dragons & in the final movie there was one chopper & usually one dragon on screen at a time!
& then i read that the budget was SEVERLY cut after production had started & Rob Bowman had indeed intended for lots of dragons versus chopper fights & could possibly have that in the sequel, so i gave it another look, not judging it too harshly & found it reasonably entertaining
