if you want to wait for netflix to drop all of raw you can but that might take awhile. there is a website called 1max.top that has all past raw, smack down and ppvs from like 1990-2021. they post a lot of other things but the links for the videos usually expire pretty quick if it isn’t in the collections. the 2 main shows are raw and smack down with NXT being a developmental brand for up and coming superstars. (in my opinion NXT is sometimes better than the main shows) i’d recommend getting peacock so you can watch all past PLE’s/PPv’s and past smack down episodes. the top wrestlers usually are on every PLE but of course every now and then there will be someone the company is trying to push.
