Avengers was a great movie. As a superhero movie it did everything it could well and left me with few irks. I sat in probably the worst spot in the theater in the second row of one of those big stadium style theaters. Digital projection and at the far left seat of my row. I spent the whole time looking up and right and it hasn’t tarnished my feelings on the movie at all.
If you liked the other recent Marvel movies, Iron Man/Thor/Captain America, go see Avengers. You’re in for a treat.
