I just watched Star Trek 2009 and 2013, although i've seen 2009 before, I rewatched it to just remind myself of the new cast and plots.
I really enjoyed these new incarnations, i'm definately not a trek fan, but I think these have a new and exciting feel.
The 2009 film is very well directed and the filming style I really like, the whole feel was very good, the same for the 2013 film, although the plot line is a bit thinner and generally doesn't hold together as well as 2009.
The biggest thing about the 2013 film is the gulf in acting between Chris Pine and Benedict Cumberbach, Cumberbach is awesome and plays the role brilliantly, where Pine, although he is trying to pull of Kirks slapdash side just isn't up to the same level. I feel it is also let down by the poor acting of Trevor Eve's daughter Alice, I just don't think she is up to this level.
anyhow, 2009 8/10
2013 6/10 but 8/10 for Khans role.
