What I didn't like....
I just saw this movie and I thought that it could have been better. Like, in many of the scenes they had the split screen in the same scene. Okay, that works in shows like "24", but was it really necessary in this?
Also, I hated the whole consecutive New Years Eve thing; considering the time era this could have all been one New Years Eve. Like, in the end, I was confused about the timing. That whole consecutive New Years Eve thing was not necessary.
Another thing I didn't like was the corny hippie rock band scenes. Those were the fakest hippies I have ever seen in a movie!
One additional thing I thought about; did Ron Howard quit Happy Days to film this? I seem to remember that there were a few seasons of Happy Days that his character was in the army in Greenland.
Otherwise, I liked this, and the end was chilling. I had to watch it a few times.
