I have; Garrod/Tifa is probably the most sincere of all the gundam series pairings. Also, the Twin Satellite Cannon is probably my favorite attack in the franchise right behind Turn-A's Moonlight Butterfly.
Yes, I have. n__n It's not the best anime out there, but it's certainly not the worst. My favorite episode has gotta be ""The Teacher's Achilles Heel," where Asako's friends try to find out what her weaknesses are.
