Wing was a show with good ideas and great suit designs, especially Katoki's stuff in EW. Unfortunately, it was saddled with some of the worst cast in gundam history. A bunch of personality-free super soldiers who have no real defining features. It also repeated the same plot ideas over and over. There's only so many times you can have characters threaten to blow themselves up before it loses its impact and just becomes hilarious.
OZ was the best part of Gundam Wing. Want to rewatch that too. I ended up liking Heero but his early antics were comical. A few years back on /m/, some scans from an artbook were floating about with some english used in big letters to address some defining trait of the character featured on that page. I think Heero's was SUICIDE or SUICIDAL. :lol
