Didn't Star Trek IV have a commentary by the writers of the new movie? That always struck me as rather bizarre...
Anyway, I'm looking forward to the new Insurrection commentary. I actually watched that movie again last night and it wasn't as bad as I remembered.
The new releases had commentaries by writers who were associated with Trek, but not the particular project they were commenting on. Sort of 'professional fan' commentaries, I suppose. This appears to be the same, while the others are more traditional tracks (glad David Carson is doing one for Generations at last).
