I finished the anime before going to bed. The anime was good. The ending left in a conclusion that either johan disappeared or it was just an illusion that he was there.
I often re-watch Black Lagoon its my fav anime, the females in that show are the most badass women in anime.(Maybe slightly bias lol) but yeah I have probably watched it about 20 times, maybe more. I have also re-watched Ghost in the Shell several times, its probably my second favorite anime. Others I have re-watched a few times would be FMA Brotherhood, Kuroko no Basket, Samurai Champloo, HxH, and Guilty Crown. I have others as well but these are the ones I re-watch the most
Of course. When you watch more than once you notice things you missed the first time. Not only that but give enough time in between, and you may have a slightly different perspective.
But the ones listed in my sig I've seen more than once. Plus FLCL, Mushi-Shi, K, Ping pong: The animation. I think I've seen Beck the most, with like 3 watches.
