Last weekend, I watched the movie
After Earth. I heard before that it wasn't great, but after I saw
its trailer and some people also told me that it looks a bit like my book,
Die Wiederentdeckung
der Erde, I just had to watch it. And it wasn't that bad.
Unfortunately, we entered the cinema hall a few minutes after the film had started already, so maybe I missed some essential explanations like why they are only using melee weapons, but who knows, maybe without explanations the movie appeared better to us as it was. :)
All in all, I'd recommend to watch it, it's at least lightweight entertainment, especially if you like science fiction.
