The movie was so good. I can't understand the 'hatred' for it :/
Agree.
Loved it. Of course it's not perfect but with a shortage of great sci-fi's in recent years, this was a breath of fresh air.
People talk about the science making no sense but when you are dealing with singularities, black holes, wormholes, parallel universes, dark matter and multi-dimensions, even the greatest scientific minds cannot agree on what makes sense. Sometimes it is OK to fill in the gaps when dealing with stuff the we don't fully understand. But suddenly everyone is an expert in astrophysics.
Plenty of great science fiction writing uses similar themes and takes similar liberties with the unknown. If you cannot go to the cinema without being able to suspend some kind of disbelief into what makes sense to you, you are always going to be disappointed.
As for exploring the themes of love and connection - it is well known that many astronauts, when cast into the void of space, have great moments of epiphany - sometimes even religious awakenings. It is not unusual that a member of crew should experience some kind of emotional sense of a higher power. It is a natural side effect of deep-space travel.
As someone else said, you just need to sit back and enjoy it for what it is. It is a well-made, intelligent, entertaining and visually stunning sci-fi blockbuster of which there are far too few. Embrace it.
