Doctor Who has always been a pretty silly show with some occasionally good british sci-fi (especially the episodes with the 4th doctor written by Douglas Adams).
But then the reboot came and the 9th doctor was actually pretty good and pretty real (the drama of the time war and all that). The 10th doctor was good though he had his fair share of silly stuff, but then 11 came around and with it also came Steven Moffat, the absolute worst.
Series 8 was a little better, but still incredibly disappointing given the show's lineage. Honestly, unless they can come up with something new and original to make it worth watching, then I personally feel like they're beating a dead horse with this show.
