Okay, all I'm reading here is a bunch of fear mongering. A prequel can be done well; if you have a good script, good direction and good actors, it doesn't matter if the film is taking place in 2156 or 2381.
I happen to believe the TNG/DS9 era has played itself out; it's tired, with 21 seasons on TV and four movies behind it.
And while I agree that in the first two seasons Enterprise struggled to stand on its own, it was no different than Seasons 1-2 of TNG, DS9 and Voyager. Seasons 3-4 were much stronger and fan favorites, and the series was heading in the right direction with Manny Coto at the helm. Manny was showing a prequel could work, so don't dismiss a "prequel" out of hand.
Besides, a movie trilogy is more finite and, thusly, can be tighter in its control of canon.
That said, Berman and Braga need to go, regardless of what they do with the franchise next.
