Well this is an interesting disappointment. The Bourne trilogy has been a dirty, fast, well thought out set of films until the final installment. The story was ultimately disappointing with characters reacting in very odd ways without any obvious motivation. I don't want to give too much away and spoil it so I will now focus on the good bits.
Fight scenes - amazing
Chase scenes - amazing
Camera angles - made me feel very sick!
Plot - poor to average
All in all a

for visuals and a

for plot. Worth seeing but don't expect to be blown away.
