Didn't Rick Berman say TATV would've been retconned had ENT been approved for a 5th season?
No, he actually said TATV never would have been made in the first place. There wouldn't be any need for a quick (and sloppy, not to mention - idiotic) wrap-up.
Although, considering how badly Braga urged to kill Trip, his death would have probably still happened. Sad thing is, seeing how out of touch with the audience (and common sense) he and Berman had become over the years, there's really no reason to assume Season V finale would have been any better than TATV.
