It's just not great either. In very basic terms, humanity finds a super amazing energy source but it is slightly unstable. An alien mothership arrives and attacks various places on earth. Shanghai has a huge amount of the energy source underground which gives the city power. The mothership begins attacking Shanghai. A group of 4 friends who were all trained as pilots/soldiers fight for their city. The action and special effects are well done, the acting is really good but there is just something missing for me. Oh and it is super soppy, lots of long glances, pregnant pauses and being upset because someone we cared about died and we didn't get the chance to tell them we cared for them even though we had hundreds of chances! Yeah, that was the most annoying thing about this film, apart from the fact someone who should have been dead at the end wasn't. Not a bad film, I would watch it again but I wouldn't choose to buy it.
