you mean the greatest and most successful period in the company's history... the era that is responsible for more legends than any other in history... the stretch of time that is widely considered the golden age of professional wrestling ... hasn't aged well?
honest question. how old are you?
No, a lot of those matches haven't aged well at all. The WWF style at the time was ridiculously cookie cutter, and it's quite obvious there wasn't a large premium placed on having "good matches" in the traditional sense as most of the dudes involved had better work before and/or after. Of course, there are some absolute gems of the era, but when we're talking about in-ring product and great matches people have missed out on, 80's WWF is hardly where you should start.
There's a reason why Savage-Steamboat is so ridiculously praised, and it's because of how much it stood out versus a lot of what else was happening once the bell actually rang. On the other hand you had the likes of Flair, Sting, Steamboat, and Windham having matches of that caliber multiple times a year.
Greatest and most successful is entirely subjective, btw.
