What? Barbra Streisand and her puppet husband don't count as "experts" on Reagan?/sarcasm
Seriously, this is what it will take. When even those with liberal political sentiments debunk this as trash, CBS sponsors may start to soften. It's a waste of time to talk to CBS -- only the sponsors matter. (That's how the Left "got" Dr. Laura.)
And the local affilliates. I'm calling mine, in Dallas/Ft. Worth, next week and asking them not to air this trash.
From the clips, promos and stills I've seen it appears that the openly hostile nature of this pseudo-bio-pic is embedded in the lighting, makeup, music, actors' expressions/demeanor and etc. It doesn't look like it will be possible to "fix" it just by editing out the most egregiously offensive scenes.
