Eh, Doctor Who is... Geez, how do I explain this without being lynched by an angry mob?
I don't HATE it... but I do think the new stuff is highly overrated. It has such a devoted fanbase, I feel like it's severe issues get completely ignored. I'll get the positive out of the way first. It does do a much better job of balancing it's silly and dark then most shows. It's by no means perfect, but I've seen it done worse.
Okay, the bad... the Doctor is a terrible character -.- I know I said the show has a good balance of dark and silly, but I don't feel like the Doctor is balanced. They try to portray him as a brooding survivor whose seen too much to ever heal or open up, but his Timelord condition has zero negative side effects, and he's on a constant sugar high. I do get that he keeps people around he can't connect with, and that's about the only legitimate character flaw he has, but the rest just boils down to 'boo hoo, I can't die, I'll get a new face, except when I don't get one, which is when I don't want one. I can die whenever I want to, but immortality is my curse, boo hoo'.
And his silly behaviour is a symptom of the worst problem. The writers are treating you like idiots guys >.> There's a reason the Doctor acts like keys being dangled in front of your face. It's so they can avoid actually explaining anything. Here's an example. The gang are locked up in a room. There's no way to escape. An unknown enemy is coming for them. They sit down and talk a while and then a robotic pig mutant shows up to kill them. Here's what typically happens.
The Doctor will mumble something brilliant, explaining the pig monsters existence and purpose in about 4 words while he 'hacks' the lock with that laserlight. Which he could have done before. A show running at a normal speed couldn't get away with this. You'd be screaming to the roof at the amount of contrived solutions the guy can just fling about. He has a Deus Ex Machina in his pocket. And now they need to kill the Robopig. How does he do it?
Brilliantly! Because there was a computer or something, and now his current lady friend has Timelord DNA, and that let's them reverse the something something on the something shift, because the Mutant's regenerative metabolism is something something reversed and now it eats itself because- no, wait, forget that, he shines his penlight on some cables and dances around yelling THATS IT. How brilliant he is.
And I think this really comes down to the characters premise. He's a 'pacifist action hero'. And that sounds interesting, but really, it just equates to someone who exists on screen, doing nothing proactive, just waiting for the mystery part of the plot to wind down so the SOLVE EVERYTHING button can fall in his lap and everyone can swoon over him when he presses it.
It sucks being a Timelord. You're constantly brilliant, you get to do whatever you want, no one ever makes you explain yourself, and you're just brilliant. It's his curse.
