You know, I would love to be able to answer this question, but all the TV I watch is either a) Asian and is meant to run for only one season anyway (
Kisarazu Cat's Eye,
Coffee Prince), or b) gets canned before it even gets a chance to jump the shark.
For further evidence of point B, I give you every TV show I've ever watched enough to call myself a legit fan of it:
1.
Mighty Morphin Power Rangers - While this show did run for a while, it fell into the same pattern of unconnected seasons with a new cast that it's Japanese counterpart, Super Sentai, has, so really couldn't jump the shark. And it
was canceled, and didn't run last year. The only reason there was a new season this year was that Haim/Saban (the original showrunners) said "Fuck this shit, Disney, we're taking it back."
2.
The Loop - Canceled after the second season, when Fox decided to turn it from its original concept of a twenty-something trying to balance his professional life in a pretty high profile position and his personal life as a, well, twenty-something who wants to act like a twenty-something into a wannabe ripoff of
The Office (making fans of the first season - myself included - go, "What the ever loving fuck Fox, what are you doing?")
3.
Reaper - Canceled after the second season, yet again (after the second season was reduced and only happened after a
huge fan campaign, because The CW felt it wasn't a good fit for the direction the network was going (i.e. - Reality TV and melodramatic teen dramas like
Gossip Girl and
90210. Exceptions being
Supernatural and
Smallville, but the latter is already on its last season and the former probably nearing the chopping block anyway)
4.
The Listener - NBC canned its airing partway into the first season, due to lack of ratings due to lack of promotion (they promoted the premiere and... that was it?!). The second season aired
a year and a half after the first season, and I really doubt there's gonna be a third one.
5.
Glory Daze - Canceled at the end of the first season. TBS claimed low ratings, and critics claimed this was due to the fact that it was trite, cliché. Also, I think it had a lot to do with the target audience having been
born in the mid 80's opposed to having
gone to college in the mid 80's.
6.
Breaking In - Canceled after the first season. To be fair, I have yet to pick this one up, but I was planning it, and I still plan to, maybe. Another victim of Fox's stupidity.
7.
Eureka - Just announced a week and a half ago that next season is the last. Again, I think this has to do with Sci-Fi (oh, excuse me,
Syfy) wanting to take their network in a "different" direction that has nothing to do with scripted TV.
The one exception to this could be
Entourage, but it is currently in its final season. (Wiki claims that the eighth season was meant to be the last one all along, so this isn't considered a cancellation, but IDK. I still find it odd the show ends as soon as I pick it up.)
On the bright side, this means I have plenty of time to catch up with the canons, since they're either closed, or will be closed soon.
