Ultimate Spider-Man #1, which was handed out for free when I saw Spider-Man 1 at the movies, is what got me into comics. I collected the TPB's up 'till Vol. 11, which is when my interest in Ult. Spidey began to fizzle. I thought that perhaps I just needed a little break from Bendis' writing and then come back. Thing is, 'Taking a break from Bendis' and 'Reading Marvel' are two conflicting statements.
But yeah, I was and am a big fan of the things he has done on that title, especially during Bagley's run.
