An ill fated yet valiant attempt at an homage to the B-grade horror genre.
It's as good as you'll get this year, fun to watch, enjoyable in some parts, the time travel thing works on a lot of levels. Don't think about it too much it will fuck with your head, remember it's fiction, theories CAN have holes. It's got that same narrative style that original Blade Runner has.
The problem with this picture is when Americans think about they're apocalyptic future it's never believable. The power of any sci-fi picture is that at some point you believe, even if it's just for a moment, there is no point in Interstellar that this happens. This movie is just another family first, christian morality played out on a green screen. If it wasn't for the intoxicants and the special effects I would have walked out! Nolan has lost what little he ever had.
