One of my biggest gripes with Special Editions is that they bulldozed the efforts of the original special effects team.
Today everything is done by CGI but that wasn’t remotely possible in 1977. The work that John Dykstra and his team did for George Lucas was nothing short of heroic. But because George got a wild bug up his ass in the late nineties, a lot of their work has been struck from the official record and now resides only in pirated versions of the original trilogy.
Honestly, it’s bullshit. Those guys are artists too and their work should have been respected.
