The good news is there's only 2-3 people on here that seem to take personal offense to any criticism, constructive or otherwise, to Scott's prequels. The bad news is they flood the comment sections relentlessly so there might as well be 100 of them.
The prequels are fine in their own way, just like the original films are fine in theirs. I'm sure when those came out pre-internet, there was similar backlash, it just wasn't as apparent. I'm reserving judgment until the final film gets released, because the way that's handled can have a retroactive effect on the previous two.
Just to play devil's advocate, why is it that any detractors of the prequels are automatically proponents of Neill Blomkamp?
Also, why do certain people act like they know exactly what Blomkamp's sequel was going to be about in relation to the continuous referencing of queens, pulse rifles, power loaders, etc? I wasn't aware that there was a script floating around the internet, and judging from Ridley's comments, neither was he.
All I saw was some preliminary concept art that was created before the guy was even officially commissioned to work. Between pulse rifle accusations, check out the very well-stocked concept art gallery for A:C on this site and compare the art to how much we actually saw in the finished movie.
