No, you haven't,
Avengers is so good even my MOM is hooked. I mentioned (about a week before it premiered) that I was planning on getting a ticket to the midnight showing, and her reply? "Oh, that sounds like fun!"
My mother doesn't really like going to the movies and had never even seen the other films in the Marvel Universe, so I hadn't even considered the possibility of her wanting to go. But I got two tickets, we spent the evenings that week watching Hulk, Iron Man, Thor, Iron Man 2, and Captain America. And we went to the midnight show together, had an absolute blast, and she
was the one that suggested going back to see it in 3D a week later! And we'll go and see it again in 3D once it hits the cheap theatre here, which should be in a week or two.
...she's also the one that suggested I cosplay as Black Widow at Dragon*Con this year, so gods help me, in two weeks I'll be a redhead in a catsuit. Eek!
