Tagging this as an "essay" is really pushing it, but it's more than just "musing"... I've thought for quite a while that you can divide
Friendship is Magic into three broad eras. The divisions aren't hard and fast, and it wouldn't be all that difficult to argue for a two-era classification instead. For what it's worth, though, here's how I see it:
Original Pony
This consists of the first three seasons – which in another reality might easily have ended up being all we got of
FiM. I remember that we were all on tenterhooks until we actually saw the first ads for S4. In the Original
Pony era, the show is strongly Mane Six-focused, with only occasional diversions to the CMC etc. The wider story is centred on Ponyville and the episodes are generally domestic and relatively low-stakes, apart from season premieres and finales. The roster of writers remains pretty stable, with only a few comings and goings.
Although Lauren Faust has said that the story she had originally planned could not have survived beyond "A Canterlot Wedding" – not least the introduction of a third alicorn princess – most S3 episodes could actually have been slotted into late S1 without too much difficulty. Other than the finale, the major exception is
"Keep Calm and Flutter On" and it's arguable that Discord's reformation, rather than Twilight's ascension, is actually the beginning of the end for Original
Pony.
Transition Pony
This covers seasons 4 and 5, a relatively short period but one in which we see some very large changes. The CMC get their cutie marks and Diamond Tiara is reformed. Starlight Glimmer makes her debut, even if she doesn't become a regular until S6. Twilight loses her home in the comfortable, homely library and has to start again in the new hard-edged castle, and in a two-era version of this post, that would be the dividing line. Many of the original writers depart: Amy Keating Rogers, Cindy Morrow,
Merriwether Williams and (one S7 oddity apart) M. A. Larson, whose sublime
"Amending Fences" provides the high water mark of
FiM as we'd known it.
Meanwhile, a number of new writers come on board, including the likes of Natasha Levinger, Corey Powell, Nick Confalone – and most notably, Josh Haber. His debut episode,
"Castle Mane-ia", is in retrospect very significant, and not only because it introduced the Journal of Friendship. It is also the first episode that
could not have been made in the Original
Pony era, being something more akin to
Scooby-Doo with ponies. Haber would go on to be a major influence on the show's direction as both writer and showrunner.
New Pony
From here onwards, we're in the modern era. Apart from Dave Polsky who hangs on into S6, all the original writers are gone, and there's a fair case for saying that the show plays a little more fast and loose with lore and continuity from this point. You rarely now get a reminder that the ponies are directly responsible for much of Equestrian Nature, not like you did in the "Winter Wrap Up" days.
FiM has become something just a little closer to a "wacky cartoon antics" show, albeit with the significant difference of characters with depth who are shown to grow on-screen.
Technically, the show is better than ever, with the sumptuous
"A Hearth's Warming Tail" being a delight for both eyes and ears. On the downside (for some) there's less attention paid to keeping the universe consistent: the composition of the teaching staff at the School of Friendship is clearly a logical nonsense. And the Mane Six themselves become less central, with the likes of Starlight, Trixie, the reformed changelings and latterly the Student Six taking some of the limelight.
So, where are we?
It's understandable that this rather changed show is not to every fan's taste, and it probably
is true to say that the quality of the writing has suffered a bit with no-one left in that department who was around for the Original
Pony days when much of the world's lore was established. However, that doesn't make today's
FiM a
bad cartoon, just a different one. My guess is that S9 will be part of the New
Pony era rather than taking off in a totally different direction, and you know what? I'm okay with that.
