I'm of the mind that tv shows need to decide whether they want to be episodic/procedural or arc based. I simply can't stand when shows try to have it both ways. Inevitably series in the last decade can't manage to elevate the standalone storytelling to make it entertaining in its own right so you basically become frustrated having to sit through the very definition of filler to get a few small nuggets tied to the bigger arc and reminds you how weak the story-of-the-week is or worse yet the entire episode is standalone.
Frankly I've seen pretty much every cop story there is and thanks to The X-Files pretty much every interesting sff spin on the cop story so I am pretty adamant that television series need to eschew cop stories unless they are true blue cop shows like CSI or Criminal Minds. All the ones that do try to have it both ways are boring--Past Lives, New Amsterdam, Alcatraz, The 4400, Fringe etc.
This is one of the reasons I dropped Grimm after the second episode--that and its campy nature was awful. SFF is so much better with heavy serialization. I'm convinced there isn't any new standalone that hasn't already been done before and done better thanks to shows like TOS, TNG, TXF.
I'm also a tv viewer that is soooooooooooooooooooooooooooooo tired of every new show trying to copy LOST with its large cast, flashbacks, fast densely plotted storytelling and non linear approach starting off with avery limited premise that constrains the storyteller. They can't pull it off not even LOST did--it always turns into a long drawn out disappointing unnecessarily convoluted mess with little to no satisfying payoffs--Harpers Island, Invasion, Surface, Life on Mars, Persons Unknown, S1 Heroes, Alcatraz, The Event, V, Flash Forward, The Nine, Kidnapped, Reunion, Vanished or they are a long plodding pretentious meditative bore like Caprica, Rubicon, The Killing, Camelot etc. That's why I have given up on most shows this season and plan to start next season with a cloean slate and hopefully the networks will have one or two consistently entertaining new programs that get back to a simple general premise with a modest ensemble straightforward linear storytelling that is heavily serialized and none of this overly complicated LOST model of storytelling that just needs to ermanently go away.
