When Whedon is on his game he is spot on. You could tell the whole movie was laced with his humor and seeing as I love his humor, it was perfect. The Hulk scenes were funny the last lulzy one my theater actually burst out in laughter and applause. Really good stuff. I was worried how they'd handle all the heros but they did a damn good job. Money well spent.

Apparently there was a second scene after the credits for american audiences only. But It was only them sitting around eating after the battle with no dialogue. So meh, nothing worth really anything special for the other countries to have missed
