I thought they were all conceptually pretty good, slightly oddly filmed and a bit corny in a way.
I actually liked the second one, even if it was maybe a bit obvious. He was taking all the things alot of people are completely buying into and then pushing them to their theoretical extremes. Its grim and depressing to watch because most people probably have a bit of discontent/ fear of where it is going, and are mostly sort of trapped in it anyway now. Or at least feel trapped in it. As someone mentioned the little touches were what made it salvageable really, beyond a pretty basic concept/storyline. and it was refreshing to see someone try and attempt a decent futuristic piece that is atleast relevant not playing on old clichés.
The last one was maybe the best conceptually I think, allthough it didn't really use it for anything interesting. Clear paralells between things like Facebook recording every conversation you had, every image you take etc, being instantly retrievable at anytime. So again I think he was taking that to the next logical extreme and showing all the problems that it could cause. I'm not talking about privacy here by the way, but the sort of extra highly accurate memory funtion we now have due to the internet. Its just a pity he didn't go deeper with it, I guess the choice of them all being well-off elite lawyers etc, was purposeful.
