If you are reading this then I will assume you know the general time travelling story from the first film.
The original Butterfly effect was a thought provoking and very entertaining film. Its lead, Ashton Kutcher, played a character who you could easily warm to and each time he altered his past (and therefore everyone elses as well) there was genuine shock and surprise each time you saw the results of his actions. Sadly the sequel has lost any charm the original had and has made a very interesting concept totally boring.
The lead character (Nick) can now travel in time looking at photos, rather than reading this time. This in itself is too easy. We all have old photos, but how many of us have old letters or diaries from our childhood like were used in the original? Whenever Nick changes the past/future there are never any moments when we are truly shocked with the changes to his life which happen. The worst it gets is that he splits up with his girlfriend. Most of us have been there before and know that however upsetting it is at the time, we get over it and it rarely destroys our life. Contrast this with the first movie where Ashton Kutcher loses his arms! This is something life changing and was a surprise you did not see coming and was shocking.
The acting is appalling from all involved. There is no chemistry between the lead and his girlfriend. There are times when the film looks like becoming a soft porn movie but even this is poorly executed. Rather then appearing erotic they are so choreographed I was expecting them to start dancing at any moment. The film plods along with all the pace and excitement of a tortoise race and the only emotion you feel at the end is relief, relief that it is all over. I only wish I had taken a photo of myself before I started watching so I could now try and go back in time and avoid watching it all together.
