Taking what the Navy has done in the past with Battleships of recalling reitrees to bring the ship. Back to life was a joy as I can remember all those 70 - 80 year old men coming back to the Navy to bring the battleships out of mothballs,it was good to see the "old salts" coming to the rescue.
The story had some minor problems but once it got going outstanding . Loved the science fiction side.
I grew up reading the Avengers and to see a movie that honored those old comics books was a thrill. The acting and the little bits of special humor made the movie, of course the special affects were exciting as well!
