the more you think about it, the more eps 6-8 feel like a collective sabotage. and it just peaks in the finale. it's really not just writing - the script itself is worse, sets are worse, cgi is worse, acting is worse (only jamie seems to be giving his 100%), extras act worse too, camerawork is worse, there is an insane amount of continuity errors, editing is worse too, the whole product just feels like a Slop.
the only moment it picks up again to its previous quality is the epilogue but then everything in it just seems deeply off. the acting is not straight up bad it's just very theatrical and lacks naturalness. there is a huge amount of references and easter eggs to the point you're overloaded by them, the amount of detail in the background is suddenly insane after very lackluster blue screen sets for the most of the episode. color grading, lighting, editing and sound feels better too but not like previously. it has this very intense vibe that hasn't been seen in stranger things before - the closest thing we've seen to it is henry's mindscape/camazotz.
