Star Trek New Voyages (and Star Trek Continues, to a lesser extent) were beautiful, and I'm so glad that they existed and I'm deeply upset with Paramount for fucking them up.
(There are 3! Episodes of Star Trek New Voyages that will never get finished because between them being shot and being released, they became explicitly illegal.)
Of course, this is because they were always illegal. They were copyright infringing, it just didn't matter until Paramount decided that fan films had gotten too good, and posed a real threat to their bottom line.
I don't think I can fully explain how much Paramount's capricious fan film guidelines radicalized me w/r/t my views on copyright.
