A little harsh. Yes, the cheese factor is high (the sets I referred to as "Frank Lloyd Wrong") and to modern audiences some of the plot holes are pretty evident. But there are shots in this that in this post 9/11 world where we are more aware of the issues facing first responders can't help but resonate. Oddly the building itself it prescient: we don't have 138 stories of mixed use, but the idea of a tower that combines residential on a narrow top and offices on a wider base was way ahead of its time in the 70's.
It's a perfect popcorn movie for a rainy night like this one in LA.
