Every TV series involving aliens is the same?
That logic means that “greys Anatomy” is just a repackaging of “ER” is just a repackaging of Chicago Hope" is just a repackaging of “St Elsewhere”…
etc.
Capturing 97 aliens and hiding them in Alaska for 66 years while another hundred or whatever continue to live undetected among us is hardly the same as unbelievably gigantic alien ships showing up in every major city across the planet, an impossibly beautiful alien leader projecting herself in the sky and announcing they are here to help us and be friends, all while tens of thousands of them, maybe millions, have already infiltrated and plot to take over the planet.
At least no more the “same” than stories about doctors in hospitals are the same.
