I enjoyed it, lots of laughs and emotional gut-checks.
I remember a few comments about the blue/yellow lightning difference. Did anyone else figure that out? Barry #1 hinted at the reason without actually saying it, but I think it's obvious if you were paying attention.
As far as the Speed Force cgi, I get that it was a stylistic choice. Everything is slightly distorted inside the chrono-bowl, so the uncanny valley stuff is fine with me.
Supergirl looked better than I expected from what I saw in leaked photos. Sasha Calle deserves another shot at the part if that movie is still in the cards.
Michael Keaton obviously got a kick out of doing Bruce/Batman again. The kitchen fight scene had me laughing out loud, especially the skillet throws matching the drum hits from 25 or 6 to 4. The catchphrase revisits didn't bother me at all. On the contrary, I smiled quietly to myself.
As always, Affleck did his job. I'm not a huge fan of his Bruce/Batman. Nuff said about that.
The Clooney scene got a big laugh. I doubt that he would don the cowl again, but maybe a Beyond thing? Who knows. I try not to spend time on what ifs.
Overall, I think they did a good job of turning a doomed mess of a movie into something watchable and enjoyable, so they can leave that behind and move on to the next phase.
Congratulations and good luck to James Gunn.
