That's Still On?!

Y'know those TV shows that should really just end
After one or two seasons, but instead they extend
Defying all reason, making no sense
Adding nothing to the story, just incurring expense?
Like Buffy season six, did we really need to see
A superhero's money problems in glorious HD?
House is another- after season four,
When it really was lupus and it all became a chore,
And I would be remiss not to mention the Simpsons
Which seems to have been going on since the Age of the Flinstones*
And this same criticism of over-length, I fear,
Can now be applied to my uni career
Til now, it was a trilogy, three classical acts-
In the first, I was nervous, in the second, I cracked
But in the third, oh the third, I earnt both my wings,
Slew Emperor Palpatine and destroyed all the rings,
Escaped Shawshank Prison, depowered Magneto,
Found my true love, just like Flyby and Cheeto,
Stopped Buffalo Bill, found Rosebud the sled
(By the way, there are spoilers, I should probably have said)
I faced down my demons and completed my arc
But the camera's still rolling- now it's time to jump the shark
So welcome, my friends, to Rory's life season four-
Half the main cast aren't even here anymore!
They graduated, dropped out, or simply got lost
(Does anyone know where I can contact Tash Frost?)
We'll go over ground that we've already covered:
Theatre, schoolwork, how I can't find a lover
There'll be remakes, rehashes and redos galore!
You will definitely think 'they've done this before'
My performance will falter, in fact I'll look bored,
and you'll say to yourself, 'didn't he win an award'?
The critics will rave, the ratings diminish
And then, we'll be cancelled and just sort of....end.
Like Firefly.

Or Pushing Daisies.

I miss Pushing Daisies.

*By which I mean when the Flinstones is set, not when it began airing. Yeah.
