Avengers 2: Age of Ultron

Positives: Opening fight sequence.  Snarkiness off the scale of the Sarcasamater.  Wakanda.  Infinity Stones.  "I have a bow and arrow.  None of this makes sense."

Cons:  Banner/Romanov, nope just not feeling it.  Spader-bot is enjoyable and splendid, but not really scary.  And finally enough with the "heroic sacrifice" bit.  The only thing even close to a surprise with it is which hero gets blasted.
