I saw Slingshot early as part of AMC's Screen Unseen. As a self-proclaimed sci-fi junkie, I approved of the selection. Knowing zero about the movie beforehand made the experience even better. Everything was set up for success.
Yet success was not achieved. And it's pretty clear why. There isn't nearly enough substance for a full length movie. Very little happens, making the viewing experience fairly boring. I watched the trailer afterwards and it's more exciting than anything in the movie.
The best part is the cast with good performances all around. And there are some interesting story elements that come into play late. But by that point I was mostly checked out.
If you feel underwhelmed like I did, try Sunshine (2007) for a significantly better experience. More exciting and a cast that dwarfs that of Slingshot.
