My take on any art is not to analyse, but just to go with the feeling it evokes in me. If I get a stirring, then it's done its job and I like it. When looking at other pictures of the rabbit on google, Monet's haystack picture appeared. It also stirred something in me, I really liked it.
As to the rabbit.. I recently rewatched Space Oddity for the first time in decades. It blew me away, it is just timeless. It may sound odd, but that rabbit evoked similar feelings to the film. It's generally photographed in stark white rooms, standing alone. It makes me think of that obelisk in 2001, with its lack of features. It makes me think of HAL and the surface gloss of friendliness. Being stainless steel, it makes me think of it in the year 3000, just sitting there timelessly in the same white room. It could be in the final scenes of 2001 where the guy gets older and older. It is an ominous feeling, a timeless feeling (it was made in 1986), against an instinctive 'ooh its a fun balloon'. I've also got a weird love of stainless steel.
Anyway, that's my personal experience. If you look at it and just think 'it's shit' then that's perfectly fine.
Arguing over subjective experience is clearly absurd.
When many people experience similar subjective experiences, the artwork becomes famous. But I don't beat myself up if I see a piece of famous art and it does nothing for me, that's just the reality, maybe in a decade I'll like it, maybe not.
I have to say, a decade ago I used to be in the 'that's not art' brigade. Maybe getting older I'm more aware of going with heart over mind with art, music etc. In this modern world of consumerism, eyes down on phones/ zero attention span, I'm impresed at anything which evokes a reaction.
