Honestly I had low hopes for this anime before watching, but it surprised me. Excel Saga isn't overrated, it is still underrated. Are you looking for a waste of few hours of your life? Go elsewhere. Excel Saga has everything what good anime should has. It is certainly a good anime, but I don't feel that fascination. Excel Saga sets the standard 10/10 for anime anime series. Few bad reviews here to obviously scare people away. Compared to other crap made in 1999 it is excellent anime. Play the anime right now, don't waste your time.
