It's certainly an interesting project, and addresses an important concern (link rot). But the security implications of archiving arbitrary sites/js and then running that on your own domain are rather horrifying to me (especially if this would be used for any user supplied links).
Personally, I'd rather have a service that automatically submits any external links to an existing archiver (archive.org) and then falls back to that source when the original 404s, rather than serving those pages/videos locally.
Use those to start a new MCU. An MCEU or whatever lol.
I personally think the current iteration has too much baggage. Too many mediocre to downright terrible movies post-Endgame that would have to be slogged through to get the X-Men or whatever else. Too many dropped plotlines, and too much wasted potential.
They've already introduced the multiverse, so they can treat the X-Men as a soft reboot. If it goes well and they have a vision that requires it, they can merge it back into the current MCU to pick up whatever plot they were already building towards, except with hopefully better writers and revitalized creators.
That, plus their output should be limited to 1 or 2 movies per year, max, and no TV shows. Or if they do have TV shows, keep them completely separate, like the Netflix shows were.
If they do that, I'd considering giving them another chance. Otherwise, if it's more or less business as usual, Love and Thunder and GotG3 will have been the last MCU movies for me (mainly because of how bad L&T was).
