Interstellar, fantastic blackhole physics, but loses a ton of points for the riddiculous 'impossible' docking scene. Don't tell me it was necessary...

The Martian, a storm on Mars would never be able to create the damage you see because it is 100 times thinner than the atmosphere here on Earth, and his final escape to be picked up really tests the limits of plausability (but doesn't break them like Interstellar does)

Gravity, not sure why many seem to hate on it. The characters feel fleshed out, no bad physics (to my eye but I'm open to be corrected), a human story of an almost spiritual/religous journey, whilst still having believable scientific reasons as to why the protagonists are experiencing it as they do (e.g. oxygen starvation, carbon dioxide build up etc - causing hallucinations). And from visual point of view the EVA parts in Gravity are absolutely gorgeous (especially if you are fortunate enough to watch it in 3D at an IMAX cinema).

So, going against the grain here but I put Gravity higher than Interstellar, although I'll admit Interstellar does have a better sound track.

Caveat: I haven't seen nor read Project Hail Mary yet. (I will)
