You guys are breaking my heart. Wing is exactly why I'm back in. It's BECAUSE of my nostalgia for it back when I watched it after work on Toonami.
And with Versus and Gunpla, I'm interested in learning and investing in even more.
I've just rewatched it recently with a critical eye so I'm bound to be harsh to it, but I still think fondly of it and would still say that I like it very much. Wing Zero Custom and Epyon are both must haves for any Gunpla builder as well.
If nothing else, I think it's a lot better than Gundam X and Gundam Turn A which I both think is garbage. I'd throw in Age and RecoG in there, but I didn't watch both of it past 2 episodes to actually make that judgement.
I'm sure a lot here are fans of Wing just for nostalgia and being their first Gundam.
