IMHO, the Point was driven home MUCH better, and on a much more personal and smaller scale on the show than it was in the comic/movie.
the movie just came out as gore fan fiction to me. hardly interesting.
The movie just came off as an excuse for more violent and depressing super hero action that seems tobe so prevelant these days. probably one reason why it didn't seem as personal to barry as it should have been.
In terms of characterization it has some fantastic moments. Once again, similar to the DCEU complaints, it would help people (if they want) to take a closer look instead of taking a tone and letting that colour everything.
Once Barry realises what has happened, he knows he needs to find Batman, and recreate the accident...not only does he convince a haggard, broken Thomas Wayne to accept his story, he also gets horribly burned by lightning and chemicals. And even once he is burned...he tries again. "This is crazy, you belong in Arkham."
This is a Flash story, and our protagonist displays selflessness and hope (amending for the selfishness that caused the whole situation) Yes, the story around him is bleak - but that's entirely the (flash)point...
Superman, who is kept entirely without yellow sunlight for his entire life on Earth, he doesn't even fully comprehend the word friend - he also learns the word heroes. The very first thing he does, is catch a rocket that is aimed at Cyborg. "Friends." had me tearing up a little. Great stuff. He then accidentally heat visions a few people who are threatening his friends and flies off confused and scared. Perfect blend of realistic storytelling and getting Superman right. I think the only characters that are really pushing the boat are WW and Aquaman. And that is a battle of love/hate driven ego, which as we all know gets to the best of us.
I much prefer my heroes to choose to make the right choice rather than being default good guys always - it's much more powerful. It's part of why I enjoy DCEU Superman - he struggles with his place and some peoples hatred/non acceptance, and sees the depths of what humanity is capable of, and still makes choices to be good. It makes it real.
However, CW Flash also did the idea well within its own framework. I've really enjoyed the last two episodes, and when Barry admits to the team what he did, I was again tearing up (I'm far too emotional when it comes to this stuff, haha) - it was heartbreaking with great character moments.
