As I said, voyager doesn’t work as a movie. At all.
Condensing 7 years of "How do we get back home" into a one-off film where the ship is flung out then returns... it was stupid enough when movies tried doing "part one" shtick, and the TOS movies from the 80s showed an ongoing story where each chapter (TWOK, TSFS, et al) could still stand on their own as an independent outing. Either serendipitous or as intent, I would still reckon the former is the correct possibility since the makers of TSFS said the plot basically wrote itself (and other anecdotes for the other, later films. Nobody in STIV or VI said in 1982 they were planning this whole sequence of events we saw unfold over the years...)
But I digress. VOY did attempt a "movie format" for some episodes, like 'Dark Frontier". Pretending VOY ended after season 4, could "Dark Frontier" work on the big screen? For established fans, yes. For casual viewers, no. Must everything be specifically for casual viewers? Not necessarily. Must everything be specifically for hardcore fans? Not necessarily. How to balance that is not going to be easy but it's been done before, and in some cases there was never a hardcore audience to start with so one had to be built. If TOS had none, there would have been no continuation and for the same reasons Mr Ed and My Mother The Car haven't been rebooted yet. And nobody's ever going to touch Leaver it to Beaver and not for the obvious, innuendo-laden reasons. Look at how I, Spy and other reboots were mangled and that's closer to the most predominant reason.
There I go digressing again. It's like dandruff, it gets almost everywhere... you're right; VOY - given the way it was laid out - would not stand a chance. Even as a premise, of some spaceship being flung across the galaxy and encountered exotic critters to fight and in the name of protecting the Earth - didn't Flash Gordon do that? And that was not a huge hit, despite ultimately becoming a cult classic... in other words, if there's a way to disprove you wrong I hope somebody else can think of the facets.
