I agree, and I go one step beyond:
Any "series" is BY DEFINITION, bad. If to tell a good story you need +4 episodes, you're doing a poor job. Or, what's real, you're just bloating it ON PURPOSE to keep people attached to their screens.
If Citizen Kane, Tokyo Story, 2001 Space Odyssey or any other good film managed to tell their story in <3hs, I'm sure any other of these "originals" should be able to do the same.
The real quality resides in making something SHORTER and condensed. This is when you start playing with REAL cinematic mechanisms. For example, Seven Samurai is well known for its use of motion and dynamism. Kurosawa communicates a lot without using dialogue, just by the use of movement of the characters or the background. Today's productions are just: explicit dialog > cut scene nature > explicit dialog > cut scene nature > etc.
Some stories might need longer runtimes, like Lord of the Rings or whatever "bigger universe" it is. But these are EXCEPTIONS, not the rule.
For the record, I do enjoy some Series: Friends, The Office, etc. But these are just comedies, and one could argue they're explicitly made to be "bloated" (in terms of length span).

PS: I know I'm going to get downvoted to oblivion but I don't care.
I wasn't going to downvote you till this part.
Anyways, I disagree. But it really comes down to what you value in a story. You're not going to get the rich lore of Mordor, or even Tamriel in a 2 hour runtime. Movies excel at creating character moments, and any kind of worldbuilding that isn't built on an entire series will feel shallow. Or maybe boring because it will take the entire runtime and you have nothing to attach to.
Samurai jack feels like a great example. It could have been a focus oneshot on how Jack got back to the past and beat Aku. A great one, even. But that's not what the show is about. It's showing the long term effects of aku' reign, how society adapted around it, how the next generation receives propaganda to keep serving their tyrant, and the small bits of rebellion and hope shed among it. Jack getting back to the past to undo all that wasn't why Jack is thought of as a great hero. It's the influences he had and seeds of hope he sowed among the dystopia
(And yes, now Netflix owns that).
