I like the whole anime (except for that one episode where everyone dies, which was [tornado fang]ing forced and retconned in the movies), simply because it's fun, it's epic, and it pretty much is one of the few stories ever existant which caters to the only one ideal I have that I know that will never be changed. So yeah, watching it is like watching the nonexistant speech from that one war hero or political leader who never existed, simply saying that we live because we want to, we exist because we can, and [tornado fang] all kinds of logic, facts and everything we know as true, because nothing is more powerful than the human will to acomplish something.
...but it's got nothing complex, it's one of the most simplistic stories I've ever seen, even I can admit that the characters are pretty damn basic, there's a [parasitic bomb] ton of Mary-Sues and flaws along the way. But it's THE feel-good anime of all time, and it's got an ending that makes me cry every single time I watch it, not because I feel close to any of the characters, not because I particularly like anyone in it, and I do hate quite alot of the soundtrack, but it's kinda like feeling emotional due to a national anthem, or due to a really good poem about ideals and justice. Anime usually throws stuff our way, but it's usually covered in smearing bullshit of stupid throwaway characters with alternate intentions and mysterious crap to sort out, a thousand fillers and just emotional junk to make it better for the casual fanboy. TTGL just strips off all that and says what it means without requiring any kind of bullshit to help the situation. It's one of the most western-type plots of anime I've ever seen, and that's why I like it.
