Migration of species is literally been part of nature since the beginning of time. Lost of habitat is real. The top reason for most species migrating is either lost of habitat or lack of food. What other reason why would you want the aliens to come here? To steal our natural resources ( that's been done a million times v series, independence day, the arrival, etc).. to eat us? ( That's been done a million times critters, killer clowns from outer space, twilight zone series, etc).. literally for land, food, or both gonna be the most common themes. So you gonna get basically similar story
Bringing science into it is not my point.
Like I stated, aliens invading Earth cuz their planet is dying has been a worn down, predictable plot since the 1950s.
Thru-out the decades, Hollywood has done the premise and successfully put spins on the alien invasion.
In the 80s on TV, “V” the mini-series did the alien invasion plot from a dying planet. The spin was they were Reptiles and they wanted humans as food
In the 90s “Independence Day” debuted, the spin was the aliens were just intergalactic scavengers hopping from planet to planet to survive.
Around 10 years ago, TNT did the alien invasion for their series “Falling Skies”. It initially looked like they were here for resources, but a twist came out mid-way during its run on who the aliens were. And then we got a final unexpected reason why they invaded which was completely original and different from anything Hollywood had done with alien invasions. (Not gonna spoil for those who haven’t seen it)
So if the main premise of this film of these aliens invading Earth cuz their planet is dying, it’s gonna kill the franchise if that’s revealed in this upcoming film.
Been there….Done that….No interest in seeing it.
