It's really tough to be a straight guy on Doctor Who, particularly if your girlfriend is the Doctor's Companion.
We all remember Mickey, right? Sweet, lovable Mickey who loved Rose more than anything and who was treated like dirt by her the entire time they were together. Mickey, who had smarts of his own but was rarely allowed to show it because his being stupid and blundering about was far more entertaining.
He loved Rose so much that even though he wasn't keen on the Doctor- whom he KNEW his girlfriend was infatuated with- he agreed to go along for the ride because it would allow him to be closer to Rose. Rose, who was annoyed and petulant about his joining and who did her best to ignore him whenever possible.
I loved Mickey. My heart really went out to him, not only because he was a nice guy but because he was treated like crap by both Rose and the writers. Any chance at comic relief probably came at Mickey's expense and no matter how much he loved Rose she clearly had eyes only for the Doctor. It's a terrible thing to watch a good, loyal person be so terribly mistreated and it's even worse when that person allows the mistreatment to continue because they're so good and loyal.
Mickey was, in essence, only there to be the Plucky Comic Relief. He was an example of the world Rose wanted to leave behind; the boring, mundane world of reality. He was a little dull-witted and a lot in love and his whole world revolved around Rose. Without Rose he was nothing; he spent his days moping about, pining away for his missing girl and keeping a keen ear out for the familiar sound of the TARDIS in hopes he might be able to get a glimpse of her. His musing about being the "tin dog" of the group wasn't far off the mark except I think even K9 got more respect than Mickey did.
Mickey DID finally manage to move past her and go on to get a life of his own... in a new reality. Offscreen.
Add a couple of years and another regeneration and we've got Rory. Rory has a lot in common with Mickey; he's written to be slightly dull-witted and ridiculously loyal to his girlfriend- who is now his WIFE- and more often than not he's only there to be the Plucky Comic Relief. He's had his moments; great, glorious moments, but most of the time his moments are cut off or blunted by a ham-fisted attempt to make it funny. Because a soul in torment just screams "laugh at me."
I never liked Amy's infatuation with the Doctor. Not only because GREAT GODS, NOT AGAIN a Companion was in love with the Doctor but because
she already had a boyfriend. A husband-to-be, in fact. While I'm hopeful that Amy & Rory will actually wind up staying together ESPECIALLY SINCE THEY'RE MARRIED I see a lot of Mickey in him. Rory puts up with a lot of abuse and humiliation, too, and he's still trailing after his Doctor-obsessed WIFE like a lovesick puppy. He guarded her for 2000 YEARS and the woman STILL brushes him off in favor of the Doctor. Rory may be the one who's written to be a bit naive, but if you ask me Amy is the real idiot! Some of the worst stuff has cropped up in the two-part S6 premiere.
( spoilers for Impossible Astronaut/Day of the Moon )On the other side of things you have Captain Jack, who is big and bold and clever and has brass ones that would rival the best of them. He's awesome, he's a great Companion and he's also a great stand-alone character. He joins Rose and the Doctor NOT because he's hopelessly crushing on either (or both) of them but because it seems like a great adventure. He's loyal to the Doctor and loves him, but not in a love-starved puppy kind of way. He's also bi. Or omnisexual, as I usually call him.
( more spoilers for Day of the Moon )What I'd like to know is where are all the smart, ballsy straight guys? Where are the straight guys who are in it for the adventure and not because they're trailing after their girlfriends? Where are the straight guys who are just as smart- or smarter- than the girls and who aren't afraid to stand up for themselves and others? Where are the straight guys who take pending death with a smirk instead of a whimper?
Doctor Who is supposed to broaden our horizons a bit, right? So let's start by having more female Companions who aren't in love with the Doctor and more male Companions who have a brain and a will of their own. Come on, Doctor, if you try hard enough I'm sure these types can't be THAT hard to find! It's a big universe!
EDIT: Just to clarify, I don't have any issues with the gay/bi/omni characters on Doctor Who; they tend to be universally awesome and I love them, but I'd also like to see the straight characters get some of the same backbones of awesomeness instead of being left to waffle after their girlfriends or be blindly crushing on the Doctor the entire time they're around.
