How long can a show like “Castle” really last on TV? When you look at the fact that it is procedural in nature, one way of looking at it could be that the show is capable of lasting just as long as the fans continue to watch it. We see shows like “CSI” and “NCIS” extend their runs beyond 200 episodes, and there’s not any guarantee that either of them is going to be ending anytime soon.
While it’s possible that this ABC show could last a similar length of time, that’s not how series star Nathan Fillion prefers it. Why? He’d like to see the show go out with a bang rather than what he feels would be a whimper. Speaking to Digital Spy in an interview a few months before season 5 begins, the former “Firefly” star explained that he really sees anywhere between two and three seasons as the longest that this show should go on while maintaining its high quality:
“I think something that [the United Kingdom does] really well is take shows, have incredible stories and then finish strong and wrap them up. That’s something I can really appreciate … What I don’t want to see happen to Castle is… I don’t want to see it peter out and die a slow death, and be forced out.”
Fillion also claims that he could see the show wrapping up after a sixth season, but he would also be open to extending it one more year to conclude the story in the right way.
When you look at the main story of “Castle,” many of the loose ends could be tied up within that stretch of time. By the end of a potential sixth or seventh season, Castle and Beckett could be preparing for a wedding (if they are still together), Alexis would be getting close to wrapping her time in university, and the case of Beckett’s mother could almost assuredly be solved without any problem.
When you consider that some shows do have a tendency of long overstaying their welcome, do you think season 6 or 7 would be the right time for “Castle” to stay goodbye? If you want to check out some more analysis on the future of Castle’s personal life, be sure to check out our feature here.
