The Movies Go To Great Lengths To Ignore The Netflix Shows
The Marvel Netflix series -- Daredevil, Jessica Jones, Luke Cage, and Whiny Hippie Millionaire -- focus on heroes dealing with street-level situations too small for the big guys to bother with. And that means the movies can habitually neglect these shows harder than Howard Stark did Tony. At first it made sense. Why would the Hulk give a crap about Kingpin? Would Thor investigate rumors that Doctor Who has issues with consent? But then The Defenders rolled in and introduced the full role of the Netflix shows' overarching villains, the Hand. This is a powerful, cult-like group led by immortal karate supervillains who basically run the world from the shadows. That makes them at least as terrifying a threat as Hydra, which you may remember was a rather big deal in the MCU. The Hand can also resurrect the dead and do actual magic. Oh, and they're in New York, swinging their dicks like this:
Plot holes aren't usually so literal.
That's the mouth of a miles-long tunnel under the Midland Circle building. The Hand dug it smack dab in the middle of Manhattan in order to connect our world to a weird kung fu dimension with giant fucking dragons in it. In the process, the Hand kidnapped and/or killed scores of people, attacked a hospital, orchestrated a citywide media blackout, seized complete control of the city's underworld, and infiltrated several of the biggest and most influential corporations on the planet, like Rand Enterprises. All of this right in the MCU heroes' backyard.
Danny Rand and his struggle to gain control of Rand Industries received a ton of media attention, so fellow rich dickhead Tony Stark must be aware of the guy. Both Luke Cage and Daredevil have attracted multiple headlines in New York newspapers detailing their vigilante escapades, which makes them globally known figures almost by default. Hell, even the Punisher's rampage and consequent capture and trial in Daredevil Season 2 would have made at least national news. It's nearly impossible that a certain team of superhuman protectors of the planet wouldn't have noticed that something's going on in the Big Apple.
