Its just my personal taste really. I think they did an alright job with the 2 movies to give those moments that you would remember but that for the most part isnt what counts. I think more people would love it if the game storyline was involved completely.
I use DOA the movie as an example. The movie didnt do DOA any justice for storyline. The game's is very deep plotted.
I hope they add some more characters for this one. Jin's storyline would make sense because they already made an animated movie based on the first game.
