In a perfect world, all our favorite shows would last forever. We’d happily spend the next 20 years watching Castle and Beckett grow old and grey and nerdy together. No lie!

But in real life? All good shows must come to an end. Hit crime dramedies (sadly) included.

On the bright side, many a dramedy has withstood the test of time. Grey’s Anatomy and Bones both debuted on small screens in 2005 and are still searing through viewers' tender hearts season after season. NCIS and its various spin-offs has been frontrunners on the scene since 2003.

Castle — which didn’t crop up until 2009 — is actually the baby of the bunch.

And while we may often worry about the show’s fate, Castle execs seem confident in the staying power of their witty little crime procedural. Despite its late-in-the-game renewal, Castle creator Andrew Marlowe told Wetpaint Entertainment in May, “Hopefully we’ll continue to deliver really great TV. And I think we’re putting ourselves in a great position to do that.”

We must agree with Andrew on at least one count: Caskett’s saucy end-of-season hookup certainly guarantees us a successful (and sweaty) Season 5!

But what about after that? Alexis's college conquests, the ups and downs of Caskett’s burgeoning relationship, Lanie and Esposito’s hot (and heated) tension — how long can it all last?

How many seasons do you think Castle has left on its clock? Lay it out in the comments!

Now, it’s up to the gods over at ABC!
