I don't understand the need to cast the character of Mako Mori if she had to die like that. She did absolutely nothing and died for nothing. She was a powerful character in Part 1 and killing her off just like that don't look good. I feel they shouldn't have brought her back just like Raleigh Becket, Herc Hansen and Hannibal Chau.
There is absolutely nothing wrong with the action scenes its just that the story line went down didn't have much to offer. Before the end credits roll the audience are clearly told about the third installment coming but this movie could have been made a lot better.
