Not trying to sound sensitive but when I hear someone compare a alien attack to 9/11 it annoys me. Now thanks to Vulhala, I can get if you meant what he stated. But still the tone of 9/11..... no. That was horror, watching that on tv.... the following years being a american/saudi in the united states.......... f**k that!
While watching the avengers i did not get a 9/11 tone at all.
Edit- Read you post above... I know what you mean by the audience being able to tap into.... but not in this movie. It was an 'Invasion' flick. Invasion movies were coming out before the events of 9/11 and the fact i hear someone comparing a story that has been used for YEARS to 9/11.... But no hate. I still love ya <3
