Unfortunately, the final issue of Wolfman and Cockrum's Star Trek: The Motion Picture compounds all the problems they had in the second issue. While they're skilled at densely packing scenes with characters and dialogue, Wolfman apparently can't cut back on the events enough to give the issue a good flow.
He really needs another one, especially considering how little science fiction spectacular Cockrum gets to illustrate. Most of the really visual space scenes are restricted to a small panel, something quick before all the talking starts again.
Wolfman does make some big changes to the movie to streamline the story. Some of it is shifting the dialogue around, but there's also a part where he throws Kirk into a scene where he not just isn't in during the movie, but doesn't serve any purpose. It's like William Shatner's ego influenced the comics adaptation.
It's not terrible, but it started stronger.
