Still enjoyable, but I can't believe I glossed over the acting & dialogue

Rating: 6/10 (9 May 2013)

When this came out it never made much of a splash here, but I loved it as a cult sci-fi movie. Noir and off-beat, some interesting effects and a concept that, whilst not exactly new, was about to be re-done for the Matrix a few short years later.
I watched it and re-watched it a numberof times in the early 2000s, but it's been about a decade and I decided to sit down and enjoy it again. How did I ever get past the stodgy acting, corny dialogue and clunky exposition? These are things that I usually don't even become aware of unless someone else points them out?
If you haven't seen it, give it a try - it's got lots of merit, but for the most part it seems like the actors are being asked to do long division in their heads while their delivering their lines - that vacant look and lack of emotion just brings the pithy dialogue into focus all the more.
