The script is definitely good. With the magical touch of Christopher Nolan, it should hopefully raise to the Nolan Level. And as some insights, the plot itself is vast. Extremes of sci-fi is touched in this movie. Intelectual enthropy, time travel, ethic impact and anything else you could ask. The ideas are touching and deep(Wachowski deep). So yeah, can't wait for it :)
McConaughey, the film's leading star, told The Times, "There's scope, major scope, which means a lot of things have to be coordinated. But at the same time, when you're shooting it moves incredibly quickly. He also added that the subject of Interstellar and involvements in the writing process combines an original idea by Christopher Nolan. It's very personal story to him."
