Doctor Who isn't that cheesy these days. Just go back to 2005/2006 and you'll realize how far more adult it has become recently.
Next weeks looks good... I liked tonights episode but it ran a bit flat in parts and felt like the writers did a bit of stretching to cover the airtime. It was enjoyable though, felt more like proper Doctor Who (not that I hated the opener story).
I don't mind the sonic sunglasses for now, it's alright for a novelty and a little joke at wearable technology catching on in our culture. I can see a screwdriver returning at some point this series though, probably a newly designed one since the Matt Smith one looked a bit ridiculous and large (looked almost like a joke toy tbh), not very fitting for Capaldi who is generally a darker and more serious doctor compared to Smith's incarnation.
Also did anyone else think Clara was going to die at the end of the episode?

I was expecting her to die from a ghost or die in the flood, and there be a running death theme with her this season (Rory Williams teas).
