Watched Interstellar again. It's been a while. Mixed feelings about it.I think it's an amazing movie. The robots are some of the coolest things in sci fi and as you say the music is incredibly fitting. The love plot has weird moments but mostly works I'd say.
On the one hand I find the "beings" aspect of it just not good. It's also really long. Part of the plot shouldn't work.
But I think the music does wonders to keep the intensity, so even if it's been 10 minutes since anything has really happened, it doesn't hurt because it builds up anticipation wonderfully. It's also a pretty emotional movie.
Also watched Isn't it romantic. Pretty funny film!
