One of you fine gentlemen recently posted about rewatching Sopranos and Deadwood over and over, and as someone who for reasons I cannot recall missed out on both of these shows thought that that is a pretty good recommendation to at least check them out. I recall also seeing recommendations for the likes of The Wire and Entourage, which are again shows that I have never checked out for some reason.
Aside from hopefully getting some good content to watch there might be others in the same shoes, so here is your chance to spread the love. If you include a sentence or two about why you recommend a certain show that is very much appreciated.
X-Men the animated series
Batman the animated series
Spider-Man the animated series
The Tick
Gargoyles (seriously Disney went hard)
Spawn and Aeon Flux if you're into that
As a teenager during Gargoyles original run, it felt very grown up during it's run.
