The first season of Iron Man is one of the worst seasons of any Marvel cartoon. The episodes are tedious to watch and each episode of the first season is your standard good vs evil style battle. Mandarin comes up with some nefarious plan to destroy Iron Man or the world and Iron Man and his Force Works team try to stop him... yawn.
Thankfully, season two saw a new production house producing the series and the show vastly improved. Unfortunately, season two was the last of the series after poor ratings killed it.
The series originally premiered on Fox Kids in 1994 and lasted until 1996. You can currently find the entire series available on DVD from Disney Home Entertainment. I urge you to check out the series, if only for season 2.
