>>305401/a/ is pleb as shit these days and you can just watch whatever's seasonal basically, but it wouldn't hurt to watch the /a/ staples either
>Neon genesis>Cowboy bebop>K-on>Code geass>Gurren Lagann>Haruhi>FateOpinions aside these are the main shows that still get regular threads, once you've watched them you'll be able to jump in to just about any /a/ discussion but if you want to take it a bit further and appear as a true /a/utist go watch a couple of 80's shows then start lurking 3x3 threads and watching the obscure/boring shit that gets posted there and use them for shitposting
