What a lame open-end. All of that, and it didn't even conclude the most interesting plotlines and intrigues, it just rushed the action scenes.
On the other hand if it continues from then on, it'll just be new "heroes" popping left and right. And this so-called choice about civilization and technology, is a wet fa** before the explosive diarhea. Either he chooses to block it all and thus, nothing really happens, or he let it follow its course and adapt to it and it might be interesting for a while but it'll get old quickly and there won't really be a better conclusion than this open-end anyway..
Fuc*** if you do, fuc*** if you don't.
