"Hot Skull" is definitely better than I expected. It's far from perfect of course, but still quite a solid sci-fi from Turkey. I would not mind a bit more "sci" in it, they did not really go much into the explanation of jabbering throughout the series.
I was disappointed in the last episode, though. It felt rushed, and not so much in the story department, so much as in production. It felt as if actors have lost their edge and their performance got worse for no apparent reason. Although, I was watching it with English dub, so maybe it was the dub problem, and not the actors.
Nevertheless, I would not mind seeing a second season.
