Well, the Interstellar gripe is because I'm a secret operative of the Guild of Botanists (we have decoder rings and when the triffids come we won't need glyphosate; oh btw, if you read this, you now have to die, sorry, but it is a secret society). It must truly be hell being a physicist, and not just because of the obligatory tank tops (though I'm sure they don't help). I can generally suspend belief high enough that it refuses absolutely to look down. Anyway, the movie had enough bombastic spectacle to make it entertaining, though I wished they'd not bigged up the 'real science' angle since it wouldn't pass a GCSE. That, and I suspect, some creative dodging to avoid whispering global warming (a bit of Googling reveals that the nutty squad have identified 'hidden' global warming references, proof that you can't even hide the truth from the perspicacity of the truly ignorant).
Anyway, Interstellar was a mere pretender to – oh you started this – Prometheus. Weirdly, I have to watch that movie, it's compulsive, like watching people crash expensive sports cars into hard, non-negotiable objects. There's no one plot hole, they merge. The entire movie is a plot hole. A great, dark swirling mass of nonsense from which no sense can escape. It starts with a backward DNA helix and corkscrews itself into fractal incoherence. I dare anyone to describe any one scene in that movie that even vaguely acknowledges common sense in passing. The plot crosses the road to avoid sense, like it's a charity mugger blocking the pavement. As for individual holes, the entire plot might as well have been carpet bombed by an over-enthusiastic squadron of B52s. I think the popular theory is that it's supposed to be confusing so a sequel can come along and knit it all back and we'll go 'ahh, that's clever'. Hah, that'll be like digging a hole upwards.
There's too many favourites in that movie. There's a fantastic Dan Brown pale-eyed silhouette moment when David, our superintelligent android tries to see a hologram better by shining a torch at it. On that basis, I don't think we'll be welcoming our robot overlords any time soon.
