The musical score as Thanos rests on his porch.
The imagery combined with Alan Silvestri's score perfectly paralleled the emotional connection to the events that took place. It's very rare that I experience that in any movie, let alone an MCU movie. It was so solemn yet strangely expressed what I imagine Thanos to be feeling at that moment -- sadness and relief beneath a smile of contentment. Destiny arrived. Destiny fulfilled.
Follow that up with the Avengers theme played on the piano as the "Avengers Infinity War" title faded to ash after individually listing each actor's name... Perfection.
It was beautiful to hear how dead silent the theater was.
We now have complex villain who finally won. He literally is in sole possession of every infinity stone. HE SHOULD NOT LOSE.
And that's what will (hopefully) make the next film so satisfying as an inevitable goodbye to at least a few of the founding members.
Of course I know that my feelings aren't necessarily shared by everyone else. Hell, I watched with my fiancee and she was pissed that the conflict wasn't resolved. My old boss texted me out of nowhere (we used to have Marvel conversations all the time) just to tell me how pissed he was that he had to wait another year
But to me... as someone who loves the MCU, and perhaps isn't ready to let the original members go without coming together one more time, it's the greatest ending I could've hoped for. Give them the deaths they deserve in a film that isn't
as bloated. They deserve character moments that they didn't get with each other as core members in this film before they die.
Maybe IW and/or Avengers 4 won't be the best MCU movies (I believe that still goes to TWS), but collectively, I have a feeling that once A4 is over, I'll be able to look back at the last 10 years of Marvel and this Thanos story arc with the same feeling of content that Thanos had at the end of IW.
