vid is quite good but I dont like that rewinding the action whole time back and further, if you use that few time as FX its great but if its still repeating it loose its effectiveness and sometimes it confuses you and you loose interest and thats what you dont wanna
and at the end seeing same scene but faster behind titles ...again repeating is very powerful tool of editor and got very efficient impact on audience so if you over use it its then boring, thats my comment as editor
but idea is great with that rewinding and look...
