I'm sure many felt that way about Andrew Garfield when he was Spider-Man. Believe it or not, people, Garfield's version of Peter Parker was relatively popular when that series was current. I remember a lot of Raimi fans hating him because the Raimi series was rebooted but after TASM came out, there were A LOT of fans of his portrayal (me being one of them at the time). Tom Holland aka FEIGE'S Spider-Man was introduced in Civil War and in very first appearance, easily topped Garfield as the best Spider-Man.
You could say the same thing about Jack Nicholson. People thought he couldn't be topped and then Ledger came along and blew him out of the water (no disrespect to Mr. Nicholson). We don't know what Feige's version of Daredevil will look like and it could very well end up being better than the Netflix version. I know the aesthetics are going to be better, that's for certain. We'd probably get a Daredevil with a superhuman level of agility like Spider-Man.
You have to wait and see what/if they do anything with the character and then judge. Because as it is now, the Netflix version simply does not fit into the MCU proper. They are made by two different teams with two different styles and now we're hearing they did not get along. Likely because of Perlmutter.
This argument holds no water for several reasons:
1 - The Amazing Spider-Man was never conceived as an MCU film. Daredevil on the other hand was conceived as being in the MCU since the show started. It has easter eggs for movie events, etc.
2 - The show DOES fit into the MCU proper. Is it tonally similar? No, but are Ragnarok and TWS tonally similar? Just because the show offers a different edge and tone doesn't mean it doesn't fit.
3 - Ledger came almost 20 years after Nicholson. After 20 years, no one expected Jack to come back and people were by that time ready for a new version. This show just ended now. I bet you if they made TDK in the 90s after Batman 89 set in the same universe, then people would have been upset with a new Joker then.
4 - What is going to honestly be different about Matt that warrants a new version? Is he still going to be a lawyer? Was his dad a boxer? Etc. It's not like they radically changed the character. He's very faithful. So why come in and cover the same crap we've already seen?
5 - Few would have argued Garfield was the definitive Spider-Man. I've been on here many years, and the Spidey forum is one of my most visited spots. That was divisive from day 1. The day Daredevil came out, it was universally praised and particularly Vincent and Charlie are praised in their respective roles more than your Garfield to Holland example. If they recast Spider-Man tomorrow with someone else, do you think they would be universally accepted day 1? It's a closer example.
6 - Even in the case of the most high profile recasting, Edward Norton, TIH has always been considered cannon. Is it referenced as much as the other films? No, but William Hurt came back as Ross and they reference Harlem and such. Why is it too much to ask for Daredevil in the future to have the same treatment?
7 - The Netflix shows were billed as being in MCU. If you remove them from continuity, effectively all Marvel TV is removed. So if we're picking and choosing suddenly what we want as continuity, what is to stop them from doing this for future movies eventually when they want to put in a new Captain America? This ruins one of the most basic appeals of the MCU for me, the fact the stories are connected. If they're only connected when they want them to be connected, then why should I care about everything that comes out? Maybe I will pick and choose what I care about, also. Starting with Daredevil. Reboot the show and show me you don't care about continuity, then I will come in equal measure and say I don't care by not watching it.
