That’s it’s only problem (for me), it’s just a string of scenes spliced together and doesn’t, really, have a story to speak of.
I still love it unconditionally, though.
Well, I'm not sure about that. It depends on who your protagonist is. If you're writing from the POV of your protagonist (be it in first- or third-person narrative), it's absolutely vital for your protagonist to have a growth arc.
(Second-person narrative is rarely done, and camera view is often reserved for movies. The biggest difference between first/third-person narrative and camera view is that in the former, the story is all about your hero/heroine, and in camera view, your camera tells the story.
So, in the former, you can only see things from the POV of your hero. Your reader only knows what he knows. On the other hand, you can dive in deeper and show your hero's thoughts, feelings, and senses (sight, smell, taste etc.) This works
especially well if your hero is handicapped in some way (partial sight etc.), or even if he's
temporarily handicapped (e.g. wearing a great helm that defends his head but muffles his hearing and narrows his field of vision).
In camera view, you don't have all that. But now, your reader knows what all your characters know, to compensate for all that. OTOH, you can't dive into any of their thoughts or feelings. If you do, that's head-hopping, and can get
really confusing).
So what's all that got to do with HHGTTG? Well ... Zaphdod, Trillian, and Ford don't have growth arcs. That leaves Arthur and Marvin. Does Marvin grow through the story? No. Does Arthur? Not particularly. He is slightly less puzzled by the end, though, and more determined (e.g. not letting the mice have his brain), but that's arguably a survival tactic, not Arthur growing as a person.
So, yes, HHGTTG does not
really have a story.
In HHGTTG (the film), I would argue that the hero is Marvin. Why? Because, although his attitude never changes, his passivity changes into activity. He
does realise where his problems stem from, and although he is powerless to change that or save himself, he can do something to save the others, and he ends up saving the day despite himself. Congratulations, Marvin! But as he would say: "Gee, thanks. Ghastly, isn't it?"
