Neither of which warrant the movie being retconned. For all of its problems, it's still a decent movie and a damned fine 'ALIEN' piece.
While I agree with much of the points above, we need movies that step outside of our comfort zones and that's what this series is all about. Too many times big studios make safe decisions and the result is much like so much homogenised content already on the market.
I don't see trading in a bold movie like this for what amounts to Round 2 of 'bullet proof' characters that aren't allowed to die running around doing the same things they did previously. Leave that to Disney. I need my entertainment to be be challenging as much as it is light and easy to digest. As it is, however, with Disney dominating the big fluffy comic book action scene with 'Marvel' and 'Star Wars' we need meatier, grounded and challenging scenarios as well. Anything 'ALIEN' needs that harsh edge - and 'ALIEN 3' delivers it in spades.
Blomkamp's current proposal is so much of a pipe dream. How much more appropriate would it have been if he was around in 1988 to present this to Fox? Then it would have made sense. As it is now, being Ripley's 2nd 'Resurrection', all the sense of vulnerability and apprehension that is at the core of these movies evaporates.
Ripley already has super powers (corrosive blood, super senses, ridiculous strength) by the time of the 4th movie. What exactly is there to give her now?
A cape? lol.
