Can anyone please explain why people like it so much?
It has interesting story arcs, and good characters.
Essentially, it's really fun.
I used to love it, but I think that was because it was my 'first'. Looking back, it really isn't my thing. I guess I can see why others love it, though. It's fairly original, has a good MC, good animation, decent plotlines, and a pretty solid film.
Because this was the anime where almost all the oldfags realized they wanted to be a girl.
The fight scene in episode 4 hooked me and I watched the whole thing expecting more, and then was instead dragged along for an above average slice of life series
It also had some good action and drama along the way
