Don't get me wrong this is a very good action movie.

The action scenes are strong and funny, loved seeing Spiderman in action with the Avengers.

Unfortunately the plot suffers from having to be incredibly contrived and forces our favorites heroes to be psychotically stupid in order to get the to Avengers vs Avengers that it wanted to get to.

In some way this is Batman vs Superman the good edition. Just as stupid and contrived, but much better action and punchlines.

Though if you just want a movie with good action, go ahead, you will love this movie.
