It has both good and bad aspects to it
With better acting and and a more solid plot, this movie could have been soooo much better and popular. With that being said, I still consider myself as a fan of it.
Things I thought were good about it.
The creative differences in the aliens. Such as the types of them like, the tanker, scout, soldiers, pilots. I also like how they use a lure to get the people.
The end, I thought was creative, original. They win, we lose. The inside of the ship was creepy and uncomfortable and I liked that. The credits scenes were more of a sequel set up and to give a sense of possible hope. Also the civilian view of the event is something that was cool too. The action scenes were not too bad either.
Things I didn't like about it.
The acting and characters. They weren't the brightest of characters and weren't acted too well either. Since thats almost the whole movie, it becomes a problem and distracting. The music isnt all that memorable either.
Despite these major flaws, I still enjoy the movie and consider it a bit underrated.
