Continuing Editing

We were given a lesson to continue editing which is very hard when all 6 groups are trying to work at once however we began to try and sort out our lighting problems but we could not find a resolution even with changing all the effects.
Also we believed our scenes were too slow and dragged on rather than increasing tension and building up to something.
As a group we discussed our alternatives as we did not believe our film opening was effective enough. In my opinion, I believe we should re-film as we are now much more educated in film openings, in the horror/thriller genre and at filming and editing aswell as storylines.
