To me, Gundam Wing is a show where it manage to get the male audience at the time to be amazed. It was the first time people in North America have ever see some epic mecha show that isn't from the Transformer. It have this some kind of story about 5 teenager boys come to earth to fight against the enemies at very bad odds (we're talking about the entire military force against 5 kids). This story idea and the action scene is what (for me) make us pump when watching Gundam Wing. Yea, the show isn't great and you can challenge it as a very bad TV show in today standard, but it's a stepping stone for Japanese animated as the fans want more of it and we manage to get like most of the Gundam show and movie into North America.
It also had great music and a great dub. It's the only Gundam I'll watch dubbed.
