I am waiting standing on my toes for May, 2012. I am very biased to Iron Man among all the avengers, I think the avengers are way cooler than the justice league :p "go figure!" Although my beginning with comic books was with Tarzan and Superman "from DC comics", through my brothers old Arabic translated ones. Which at the time, I did not have much interest in.
Of course the movie Batman gave another dimension to comics, then I got to know what is a graphic novel through the amazing V for Vendetta.
Summing up their Avengers in one movie is a MUST see :}
