I love going to the movies, sit me down with a Cherry Coke and some Cotton Candy in a cool theater and I'll enjoy myself. It is even better when the movie is good!!
For Mother's Day we took my mom to see The Avengers (she is adorkable because she had no idea what it was about - but she loved it none the less).
I love the Avengers anyway (I mean you've combined several of my favorite Heroes into one book/comic/movie, obviously I'll love this!)
For those less nerdy folks I recommend you know what is going on before enjoying this movie. They don't really fill in the blanks for you so a little knowledge goes a long way. If you aren't into reading (then this is probably the wrong blog for you) then you can check out the movies leading up to this one:
If you would like to just do some research check out the Marvel Universe Wiki page for The Avengers. It will answer all of your questions. Even if you watch the movies you probably want to catch up a little with the background of Hawkeye and the Black Widow.
Want to read the comics? Good for you!! Check out the character pages at Marvel for a list of the comics each member of The Avengers.
