Yes, okay, my loyalty to Torchwood
is mostly because I'm a Doctor Who nerd. SUE ME!
But I also watch the show because its POTENTIAL is so huge. You've got a diverse, quirky cast -- most of whom are amazing actors -- under the guidance of one of the most wonderfully-conceived action heroes in history. Their mandate is open-ended and they have a dedicated pool of creative writers. Their fan base is such that they can hardly do wrong, allowing the show to experiment without fear of losing popularity.
So why did the first season mostly suck? And why did the second season suck even WORSE?
You don't have to be Tosh to figure out the reasons. There are three of them.
First, the budget is simply too low, so when they attempt to pull off Doctor Who-style scenes of mayhem they end up looking like a CGI version of...well, the '80s Doctor Who. I'm thinking mainly of the "space whale" and the "exploding Cardiff" scene, which left me wondering if I'd developed an astigmatism or if it really DID look like crap.
Second, John Barrowman can only play one role well, that of the sexy, flippant, mostly-likeable hero. When forced to branch out -- particularly in the presence of more capable actors like Eve Myles, Burn Gorman, and Naoko Mori -- he's a space whale out of water. When he was forced to cry in the first series he looked like he was taking a dump. I'm pleased to report that he's a better crier in the second series, where instead he looks like a small child about to blubber. I expect this is how Barrowman really cries.
All this would be fine, however, if it weren't for the third and most heinous problem with the series: the producers seem unaware of Barrowman's limitations -- and the obvious strengths of the Torchwood premise -- and therefore constantly shoehorn emotionally over-the-top moments into plots that don't NEED them.
This is (mostly) fine in the new Doctor Who, where the characters and mythology provide plenty of fodder for emotional blowouts. But in Torchwood, putting a requisite ten-minute weepy scene into every episode is like adding emotional depth to a Flash Gordon serial: unnecessary, distracting, and obvious.
So season two's Mostly Random Arc involving Jack's lost brother ("GRAY!!! GRAY!!!") is ridiculous, and just gives the characters yet another opportunity to say "I'm sorry...I'm so sorry."
Try contrasting "Something Borrowed," the only really good episode in the series, with one of the crappy ones like "Meat." In "Something Borrowed," the Torchwood team runs around battling a sexy alien in a ridiculous setting, cracking witty jokes and being self-referential and basically having a good time. Captain Jack gets to strut around and be tough, Gwen gets to be funny, and even Rhys is a welcome (and essential) part of the episode, instead of just saying "Darn it, Gwen, YER NEVER HOOOME!"
But in "Meat" you have an overly-ambitious, budget-free bunch of crap effects, and a pointless subplot about Rhys perhaps being evil (though we know he's not), and a heavy-handed message about...cruelty to animals, or something. You even have the conscious-stricken younger brother shouting "I DIDN'T AGREE TO THIS!" and Rhys complaining that Gwen is (yes) never home, and Jack's first opportunity this season to say (snicker) "I'm sorry..." and then (yes) "...I'm SO SORRY."
"Something Borrowed" knows that Torchwood can just be FUN. "Meat" wants to be relevant and complicated and heart-rending. One passes, one fails. WAKE UP, PRODUCTION TEAM!
Add to this yet another limping climax full of random obstacles (for which each member has a relevant skill) and the main character saying "I forgive you" to the evil mastermind (where have we heard that before, a year ago, in the climax to a show which is an anagram of "Torchwood"?) and you have, essentially, a load of whatever Barrowman was trying to crap out in the first series.
It's not ALL bad. I loved the "Owen's dead" subplot, and the cast reductions in the final episode were brilliantly performed (and tear-jerking, not least because those actors represented 66% of the team's acting talent). And whenever the show DECIDED to be funny, I laughed. And I thought "Maybe they've figured it out...maybe they understand that they should titillate me, and scare me, and make me laugh?"
Then, seconds later, Gwen would start mooning about how Torchwood had hardened her, and Owen was covering up his soft interior by being a brash jerk, and somehow Ianto still had security clearance after sneaking his cyberwoman girlfriend into the Hub. Oh, give me a break.
