As soon as I saw Tony Gilroy had directed 'Michael Clayton' it all started to make more sense. That Clooney-starrer bored me to tears and had no discernible plot, and that's exactly what you get with this utterly unnecessary film as well. A film laden with needless exposition (very little is actually going on), and with relentless signposting for the hard of thinking, Bourne 4 is an embarrassment to all concerned. What passes for a 'legacy' is Jason Bourne's successful escape at the end of Ultimatum, having caused various US government spooks (led by Ed Norton) to kill everyone else in Bourne's super-spy programme. A notable target for assassination is Aaron Cross (Renner), but Cross is as good as he was programmed to be, and is soon on the run. It's hardly believable that this film was written by the same man responsible for the Matt Damon trilogy - it's clumsy, one-note and utterly bereft of characterisation. Renner is wasted trying to act a role which is offered no hint of characterisation, other than a generalised altruism whilst on the run after saving super scientist Weisz, who upon realising her predicament, offers to save his life with a cure for his incomplete conversion into a super spy. The two run to Manilla, avoid getting murdered by a super villain Norton oh-so-conveniently has on call, and that's it. Oh yeh and Gilroy takes two hours to bring this all about. The action sequences aren't much to write home about, and you have to wait for most of them until the intrepid couple reaches the Philippines, parkour and everything. It feels written to order, in the absence of any need for a fourth instalment, but nonsense ranging from Weisz's deus-ex-machina 'magic virus' through to the one-note villainy throughout make it particularly cringe-worthy, right through to the inevitable sequel set-up. I didn't care one bit about a single character and won't be coming back next time.
