My mother loved this film back when I was a kid, actually took me to see it three times in the theater... when I was about 6.
As a kid, it was another fun action movie with a lot of fun violence and just scary enough where I could boast about it at school. And, as an adult it's a fun action movie with a lot of fun violence and a plot that doesn't completely make sense, but who cares because the point is fun.
It's one of those movies that you don't expect a lot going into and you are rewarded with, well, mindless popcorn munching action that is delivered in a way that only the 80s could do.
So what's not to like?
