boring, formulaic, annoying, uninspired

Rating: 3/10 (7 March 2015)

I hovered for a while over 5/10, but then this isn't an average film...it's below-average. There's not much to recommend it other than McConaughey's decent performance.
Here's a few things that's wrong with this picture:

the daughter is, to put it bluntly, a stuck-up bitch to her Dad: surely the most undeserving daughter in the entire universe of a reunion with a long-lost father. At least that's how she was portrayed.

the premise is pure shlock daftness: it's a silly idea dreamt up as any old excuse for the journey. And I say this as a hard sci-fi fan (or rather, hard sci-fi taught me that the premise in a story was important).

the effects are cheap-looking, even wobbly at some points! How on Earth 99% of viewers applaud the effects is truly lost on me. It just looks like a budget TV version of Lost In Space.

there's a lot of crying...a lot. Cheesy as hell.

the black character dies (obviously not a spoiler).

there's some formulaic conflict later in the film which is just dumb and predictable. Don't expect high-end existentialist conflict ala Hal-9000 vs Dave Bowman.

the moments of 'tension' are anything but. They're just boring and overlong. The music doesn't fit (sounds like a hyper-ventilating hysterical version of the brilliantly-understated Jonny Greenwood Soundtrack from There Will Be Blood).

the other planets' visuals were dull, grey and utterly uninspired.

the resolution was more soap opera than science fiction...and the obligatory wormhole/psychedelic sequence was soul-crushingly down-to-Earth.

I felt the urge to leave the cinema early at least 3 times.

It's not a 1/10 or 2/10, for those are reserved for the absolute worst film I'd consider rating (something like Pacific Rim or Sphere). But 5/10 is genuinely too kind, considering all the things wrong with it.
For some perspective: I largely agree with the high scores of all the other films in the IMDb Top 20, and Nolan's last two Batmans are worth a 7/10 (Inception's an 8). Interstellar is just one of those films where I don't for the life of me understand the praise.
Recommended for emotional girls with daddy issues.
