I didn't even think about this because I watched them as they unfolded in real time... when Supergirl went to CW, you had her on Monday, Flash on Tuesday, Arrow on Wednesday, and Legends on Thursday.
I suppose it's not that far removed from when a comic book story crosses over and you either need to wait for the collected edition, or you need 1 comic from Spiderman, one from the Avengers, one Hulk, and one Cap to tell the story.
The action on Netflix Daredevil is top notch and Kingpin was probably the best developed villain of any movie or series so far. Really excited for him to come back (actually a little disappointed he isn't the big bad for Defenders).
Jessica Jones is still my favorite of the Netflix so far because it was so cerebral and twisted. I really hope the Defenders director gets more out of Iron Fist than his Season One did. If someone wants to get caught up before Defenders you seriously could watch the first and last episodes from Iron Fist (Or first two and last two) and you'll know everything you need to know. The rest of it was a convoluted "who can Danny Trust" as he wined and stomped his feet instead of being a kick ass living weapon like he's supposed to be.
The first half of Luke Cage is better than the second half and the show runners even admit that. They didn't realize until it was finished how good of a character they had with Cottonmouth. Reminds me of some of the DC movies where they kind of waste a good character like when Nolan was expecting the Joker to carry his next movie and killed off Two-Face... and then Ledger died. Then they had to scramble and come up with new villains that were sort-of-maybe-if-people-remember a call back to the first movie.
In the theaters... from Deadpool to Logan to Wonder Woman to Spider-man..... fuck. They are really hitting their stride (after disappointments like Bats vs Stupes and Suicidal ReShoot Squad). I'm so fucking pumped for Ragnarok and Infinity War that I can barely contain myself!!!
