I enjoyed the film, but I think it's extremely uneven. I have a high tolerance for this sort of thing. In my youth I watched 2001, at the theater, many times.
Also, pet peeve, apparently the title should be Intergalactic. But in these movies, when someone mentions going to another galaxy, I never get the sense they have any appreciation for just how far away that is.
Let's go to a galaxy far, far away,
(exactly how far, let's not bother to say)
but since we've got a space-time hole
it won't take long to reach our goal,
just watch out for relativistic clocks
that lose it with their ticks and tocks.
