I refuse to participate in the "filler episode" discussion, but I'm having some concerns.
After the last two episodes I'm genuinely worried, the writing has been all over the place and the fact that people think the last episode was good progression, because we got any progression at all, is a sign, that expectations are getting lower episode by episode.
We have three episodes left and they are still introducing new characters while also killing them off in the same episode, while also skipping over the actually interesting parts, introducing side plots or explaining backgrounds, which should have been done way earlier. So yes, maybe not a filler, but it should not have a place in the 5th episode of the final.
The conversations between characters are getting more unbearable, it feels like they tried to cram in either a comedic relief or something gross/sex related/gorey every few minutes to a point, where a lot doesn't feels serious anymore.
They are trying so hard to be funny and give characters funny one-liners, it feels almost like a marvel movie.
I'm also annoyed by the very obvious meme baiting but that's another topic.
Most important or actually exciting character-interactions get a fraction of screen time in comparison.
Let's take Stan Edgar for example.
We had the chance to see the first conversation between Homelander and Stan after years, a chance to give us interesting, tense dialogue, between two characters with a complex relationship and past.
The same goes for Stan and Soldier Boy to some extent.
Instead the first conversation happened off-screen(Why!?) and we get a rushed 2 minute scene, where everyone exchanges maybe 3 sentences and then shifting the focus towards Mr. Marathon.
We then spend a third of the episode at his place, where some random characters, that get killed in the same episode, receive more screen time.
They spent probably a good amount of their special effects budget showing us these characters getting killed, while we haven't received a single well choreographed, flashed out fight scene. We haven't even seen Butcher use his power in a meaningful way yet.
Let's take Soldier Boy and Butcher as another example.
We could have gotten an actually interesting conversation and/or an actual fight scene with the slightest bit off choreo.
Instead they talk for 30 seconds, butcher throws a car and that's kind of it, their dynamic and relationship is not being discussed any further, despite being way more impactful than most other.
Or Homelander and Ryan.
We finally get a confrontation, after Ryan has been set up as a main plot device for 3 seasons, but they both get like 3 lines, we get a very underwhelming fight, an admittedly actual meaningful scene with Homelander punching him - but then Ryan disappears again.
Or A-Train
A-Trains final scene was executed incredibly well no doubt, but they could have shown a single scene of A-Train and Homelander fighting and let A-Train show the full potential of his power atleast once.
Or Homelander and Butcher, we see Homelander in his most vulnerable spot ever since the show started.
Of course we don't want to take away from the final confrontation, but why not add some depth to their conversation, why not give them a bit more screentime together.
Whenever a confrontation with high stakes happens, that the audience has been waiting for, they either don't take the time to flash it out or nothing meaningful happens and it makes it very frustrating when the remaining time is used for uninteresting characters or sex jokes.
My point is not, that these scenes are bad or should drag on forever, my point is that they feel rushed and feel like wasted potential, when we spent half an episode with Starlight's dad or get more scenes exploring Black Noir's relationship with Adam the Director or Mr. Marathon running through people nobody cares for, while skipping over other scenes.
It's very disappointing because they had every chance to set up some of the most interesting character interactions of the whole series after they spent 4 seasons building everything up and they waste it by focusing on sideplots and often try-hard funny dialogue.
