The biggest issues with the workprint are that it’s missing some alien subtitles, and it contains a very obvious and fairly jarring special edition change. If you can’t get/make a modified workprint, go for v1 or wait for v2 proper. Image quality is a huge improvement in v2, but if the whole point of despecialized is to not have the special edition changes, the vanilla workprint really has an issue there.
Yep. But, to clarify, I wouldn’t burn either the 2-WP or 1.0 to put on my shelf right now. Just wait for 2.0, unless it is really your only way to watch and you don’t mind going through discs.
