Overall the film works at many levels. It had some great thrilling scenes, which will make you, jump out of your seat. The effects were not overused. Zemeckis made sure that the effects were used in the right place at the right time. You will see what I mean.
Sound always play a strong role in a thriller.
It certainly in this one. There are numerous scenes in the film where sound plays a key role. The music builds up from the beginning until to the end of the film. I can't wait to get the soundtrack for this one. It was a bit too long for a suspenseful thriller.
