Of course there is more to it than just this being a "copy" of Sleepy Hollow (it isn't, and I generally have to rewatch that movie asap anyway)! But it has things that may feel like there are quite the few comparisons one can take. There are also references to many other Science Fiction movies and books.
Having said that, the movie does not shy away from being violent and sexy (though some may beg to differ on the latter). The acting is quite fine and the story is more than intriguing. The sound design and the cinematography more than live up to what the movie sets out to do - and anyone watching will not be dissapointed. The first of a trilogy - you kind of can feel it. And it is tough to say how you'll like it if you only watch one of those (this for example) ... you may feel it deserves more or less rating wise ...
