If this is "Smart Marketing" as some of you believe, Blomkamp has done a stellar job of creating a few corners of negativity and hostility to Covenant and Ridley Scott quite adeptly; Blomkamp can only blame himself for releasing his concept art online with no prior green light to make his film. Prometheus has had a hard enough time as it is. It's flawed, but the nitpicking it endured was beyond absurd, especially when similar complaints could be levelled at both Alien and Aliens which are the two most beloved and untouchable films of the series. If you hated the explanation behind the Engineers or the Space Jockey, then fair enough, but if you want to explores the stupidities and fractured logic of the series, the first two films can't escape them either.
I think what Blomkamp has done will not be forgotten by certain people. He must have known that Scott had plans for his own films skipping in and jumping on toes was not good form. Scott didn't suddenly decide to make Covenant because Blomlamps film had a moment of interest, Scott has wanted to do these films since before Promtheus was released. For those that have already decided they will hate Covenant, this is the moaning you're going to be seeing ad nausem for years to come "but we coulkd have had such a cool Aliens 5, Scott shut it down"
That is balls.
Plus, the major criticism I hear about the Covenant trailer is that it seems somehow unoriginal, are there the same people who believe that Colonial Marines, big guns, and long dead characters is fresh and exciting?
