The acting was good (the actress was probably my favorite character in Kickass), but it suffered from the same problem as many sci-fi movies: a total lack of scientific realism.

Also, there was no explanation for much of the nonsense, including foundational issues such as who reprogrammed the androids, why they would be remotely programmable to start with, and if they were remotely programmable, why couldn't the programming be reversed?

And I found the plot pacing incredibly slow as well. About 15 minutes in, I was just waiting for the movie to be over, and in retrospect, I felt like I wasted a couple hours of my life.

There's much better stuff out there if you want to watch speculative science fiction (or better yet, read a good sci-fi book, they are less likely to let you down).
