TMP had the benefit of coming after TOS, so all the changes were easily explained by time moving on and styles changing. Like they had in the real world. Well, all the changes except for the Klingons, that needed an episode of Enterprise to explain. The one time the movie featured something from the TOS era, the photo of the Enterprise on the wall, it stayed 100% faithful to its appearance in the original series.Creative people being creative? I am shocked by this, absolutely shocked!
Oh, wait, no I'm not. Roddenberry decided he wanted to reinvent everything from the ground up in TMP. I don't see any long soliloquies on how wrong he was or explaining the tech and uniform differences. Same with TWOK.
There's just nothing there to complain about. Aside from the Klingons.
