This film has an action-packed ending featuring an incredible (for it's time) police helicopter. However, to get to the end, one must plod through the remainder of the film and that is kinda slow. The film could be a great one but wound up only pretty decent. Roy Scheider as the star was an excellent choice and he did a great job in the film. Malcolm McDowell plays the antagonist well and the two play well off each other. However, the story bogs down a bit for nearly half the movie right in the middle. Once it picks back up, though, hold on to your seat! The ending is in the WOW! category. So watch the beginning, then take a nap in the middle to rest up for the end. 6 out of 10 from me.
