Dark Brotherhood was trash

So I just beat the Dark Brotherhood questline, and I have so much issues with the faction in this game:

First of all, I'll say I appreciated seeing Nazir again as it makes sense in Hammerfell, but his character was butchered so hard. Done is the snark he had in Skyrim, now he's just an edgy boring assassin that always rave about Sithis, which makes sense lorewise but is just pretty boring here.

Continuing on the characters, especially Marz gro-Malog was straight up annoying with his constant complaints, like dude do something instead of staying all day long in the sanctuary.

The questline itself had some alright quests >!(I did not expect to have to kill Snaps-her-Belt)!< but most were boring dungeons, it was even worse than Skyrim. Having to do 3 radiant assassinations between each quest got annoying especially when I still had to do this before reaching the Listener rank.

But the overall narrative is what killed it imo, I still don't get how we got caught by the Cult of Satakal when we never interacted with them; then boom whole sanctuary is dead (which is the same as Skyrim which is lazy af). Whole questline then is even more boring cultist dungeons, and besides, we end up being the good guys somehow? It's even worse than ESO as well which kind of does the same with you basically killing the Inquisition.

Finally, I'm not usually too demanding on the visual design for the armors, but having green as the main color was certainly a choice (guessing they tried to emulate real-life special military agents which is super stupid).

Overall, really disappointed. What's you guys' take on this?
