The movie is definitely a good movie, I felt as though it missed something....
it started badly and was spoilt for me because it was too dark during the first 5mins,in which I couldn't actually see anything at all.
However livened up a little when the main star John took his place and the movie started to form.
after a couple of unnecessary scenes and an irrelevant love triangle of the girl interest the background was introduced. and the sci-fi fans was finally relieved to learn the backdrop of this story.
the end left the audience yearning to follow their adventure. I know this movie will result in at the very least a trilogy.
I would give this movie a 7.5 out of 10 but as I am reduced to 5 I will give it four!!!
