He was trying to do everything he could to prevent Trump. That meant holding his tongue so as not to encourage people against strategic voting. It's a very dumb system we have, but it's not Bernie's fault we're in it.
Now that the general is over, he can speak his mind again. And probably a hint of getting ahead of the Democratic Party's inevitable blaming of the left for this loss rather than an ounce of introspection.
I love Reign of Fire. And honestly I think the CGI has held up surprisingly well for a 2002 movie (although not at all perfect).
