Stranger Things S5 - 7/10
Stranger Things - Whole Series - 8.5/10
S1 - Solid "goonies" x "IT" coming of age story
S2 - Solid "alien" x "thing" authority trying to control something way out of their league tropes
S3 - Solid "mallrats" x "Red Dawn" x "grindhouse" narrative about the death of small town America, the red scare, and mall culture.
S4 - Solid teen slasher flick / 80's horror story.
S5 - Solid "the power of friendship" and "by our powers combined" narrative.
A satisfying ending to a fun series. Missed opportunities? Yeah. Strange plot holes or leaps in logic? Yeah. Fun with a solid emotional core? Yeah.
As a series, Stranger Things S1 was a masterwork that dipped in quality for subsequent seasons but never so much as there was not something to find entertaining or compelling as the show went on. It was almost like a sort of mini-anthology of 80's tropes that were serviced by the primary narrative. It wasn't done perfectly, but about as well as anyone could expect.
S5 felt off initially. I suspect it might be due to Netflix's second screen rule being hardcore enforced: assume the viewer is surfing while watching, so you have to assume they just looked up from their phone and reexplain whats going on every 10-15 minutes to keep them engaged. Joyce as a character was essentially reduced to a plot device that had to act bumbled and confused about what was going on so other characters had an excuse to explain what just happened and what was about to happen for the viewer's benefit.
As the season progressed however it became less bothersome, and I appreciated the show's willingness to just go *out there* when it came to reveals. Would it have been nice if the series had been planned ahead and we had gotten some nuggets of the final season in earlier seasons? Yes, of course it would. But given that some amount of "seat of the pants" writing was clearly happening, it was all tied together remarkably well.
The cast was huge, and that definitely hurt the show. Lot of parallel narratives (many far less interesting than others), fan service, flanderization of characters (i.e. Nancy is Rambo, Murray is cranky Jew who speaks wisdom, Joyce is confused and worried, What does Jonathan even do here besides unhappy relationship with Nancy, Hopper is overprotective Dad, etc etc etc). The military subplot is also deeply frustrating, and holy shit did they waste Linda Hamilton. Nevertheless, I appreciated the extended epilogue that gave emotionally satisfying endings to all characters except one (and you know the one I'm talking about).
Overall, if you're a suburban kid of the 80's or 90's, you will LOVE stranger things. You will fucking love everything about it, it will tickle every god damn nostalgia bone in your entire god damn body. Think of that scene in Ratatouille with the critic eating the title dish, transported to his childhood where everything was simple and he was loved unconditionally, that is what this series will do to you. Flawed gem, I look forward to watching the whole thing start to finish with my kids when the youngest hits double digits.
