Look, yes it sucks, I'm one of the MS owners that don't get Theater mode. But hey - consider the plight of the person who bought a snazzy new, nose-refreshed Model S in September of 2016... stuck with AP1.
No Summon, let alone smart summon
No nav on autopilot
No auto lane change (signal triggered only, IIRC)
No Sentry Mode
No Dash Cam
No hope for FSD
All of those things became possible if you'd just bought your car one month later in October of 2016. ONE Month!
Oh, but those AP1 owners were loving it while the October build owners had no Autopilot at all for almost a year...
Also consider the absurdity of being upset because you can't watch Netflix in your car. Wow how far we've come.
Pair a good LTE tablet with your car's bluetooth and presto! Netflix in your car, for just a couple hundred bucks.
