I'm 49, so pretty old. It really depends on the quality of the remakes. And as we are deep into RPGs, the idea of alternative realities is an easily accepted situation.
For Superman I actually prefer more recent TV series 'versions' to the movies, I really liked Smallville and the newer one were Superman is a dad is also interesting, and of course the older TV series '93. And I watched those old movies before any of the TV series.
Battlestar Galactica, grew up on the old series. Which still has a certain atmosphere and quality similar to the A-team series. But the remake was by far the better. But was it a remake... What has happened before...
Star Trek, I actually dislike the original series. The movies are OK. But I actually liked the remake of Star Trek.
Star Wars is difficult, I like the atmosphere of the original trilogy, the prequel trilogy creates a whole different atmosphere, which I don't dislike, a different era. I detest the last trilogy. But none of that is really a remake of the original. The closest I think that got to remake levels was Rogue One, loved the atmosphere of that Rebel era, but I really disliked that they actually filled a hole that was the
perfect pnp RPG story to fill up as a campaign.
I like the remake TV Series of Daredevil and the Punisher (Netflix).
And should we mention the LotR movies, there were movies before that, I like the trilogy from the 2000s.
Again, it really depends on what, how, and why.
If someone ever did a remake of Babylon 5, they would have huge shoes to fill.
