That said, I fail to see how Arrow showing up on Flash or Felicity on Legends or whatever would take away anything from the main characters. It's not like other episodes, don't have other gueststars pretty much every episode who take a bit of a spotlight.
The difference is, those gueststars don't have their own show usually.
So they do not get billed as special guest stars.
But they always take as much screen time away from the main characters as the story requires.
Felicty makes every scene of every thing she's in about her. She starts crying and whining at everyone, and takes time away from everything. There hasn't been an episode of Arrow since maybe early Season 3 that wasn't all about Felicity.
Most people probably don't mind watching one episode of a show they don't watch in order to follow the crossover.
I'm starting to think we aren't watching the same Arrow and Supergirl shows.
I'm pretty sure they do if they loathe the show its crossing over with. I'm not watching
Felicity (the real name of the show that airs now, Arrow was basically cancelled after Season 3 and replaced with Felicity in all but a technical sense) or Supergirl (aka
Cat Grant: The Series), so since I'm not watching the shows we definitely aren't watching the same shows.
I watch
The Flash and
Legends of Tomorrow, which has superheroes doing super things. I don't want to see a soap opera about a drama queen who likes to cry and have relationship drama and sometimes uses computers, so I don't watch
Felicity.
Supergirl is a show with a great main character, a good supporting character (Martian Manhunter), and writers are some of the worst mainstream television writers ever, and second worst in the history of superhero TV shows (the first being the idiots who made the Wonder Woman pilot a few years ago). Whoever decided that
The Devil Wears Prada was a good thing to base a Supergirl TV show on is a terrible person who should be banned from anything more complex than writing the back of a cereal box. So, those are the shows I don't watch, and don't want to see crossover with the good DC shows.
I honestly try not to go off on Felicity or Supergirl, I don't hover around the threads or anything. But, its a bit hard when Greg Berlanti & Friends won't stop shoving them in my face. Its honestly more depressing then anything, Arrow was a great show for the first two seasons and Supergirl could have been great with different people in charge (and different writers). Its bad enough that
Supergirl gets Superman in Season 2, which means I have to watch at least 80-90 minutes of Callista Flockhart and the terrible Supergirl writers because I can't skip a new superman. Even if he's being done by idiots, that's too big a deal for a superhero fan to skip. That's enough terrible superhero TV for me without having Felicity shoved onto the two DC shows I do like.
