Surprisingly pleasurable. I had this on my list of movies that intrigued me for some time. I had forgotten why I wanted to see it. I begrudgingly decided to watch it anyway after all this time. It seemed to be a cheap, paranoia movie. I expected to be left wanting to see anything other than shadows and cliffhangers. I was very much surprised. This turned out to be a very good sci-fi movie. I recommend seeing this. It was worth the wait.
