An ID4 sequel had better be done well though. Roland Emmerich movies haven't been particularly great after ID4 was made. Godzilla, 10,000BC, The Day After Tomorrow, 2012 are prime examples of how bad his movies have become.
ID4 and Stargate were Rolands only great films.
With that in mind, I hope the sequels for ID4 get CANCELLED. They would suffer the 'sequel suckage' curse. And with Roland at the helm, that curse would probably be amplified.
And that's why I'm not too fond of sequels, the plot will be predictable, acting will be crappy and of course there will be crapload of special FX, also expect those dumb monologs like : god save us all (second later, country anthem can be heard) or silly ones like : die.... you ugly mother f....
.... that latter one was what killed AVP in the first place, then plot gone and everything else was chain reaction... same will be here I'm affraid... when Roland runs out of smart dialogs he will put there few F-words and say : 'it's settled
' ... no it isn't settled... why can't we get movies like Aliens or Predator(originals from 80s') (not similiar in plot but in quality, climate, acting etc.etc.etc.)
