I wish I hadn't ruined my first watch of Steins;Gate by starting from one of the last episodes. It got me excited, but there was so much stuff referring to earlier episodes that made me realize I'm not watching the first episode. I'm waiting just a bit longer to restart watching. I did the same with Battlestar Galactica's last season and got all excited like "Holy shit this last season is going to be crazy" before realizing I just completely ruined the whole season for myself.
