I bought this and watched it when it first came out... but I must have been distracted while watching it the first time because I didn't go back to it until I was watching some of the newer Avengers movies. I was confused about some of the story line and decided to go back and buy all the Marvel movies and start watching them in order. I was told that I didn't remember this movie because it was so bad.... but after watching it (I think for the 2nd time) I really liked it! I love the humor that is put in on occasion to help offset the seriousness of the storyline. There were some parts that I felt were a little over the top, even for Marvel, but I think the movie was really well done.
Pro tip: don't watch the Thor movies out of order or some of the important parts of the storyline will not make sense! ;) Oh... and bonus features on all these movies are totally worth watching!!!
