The Arrowverse just keeps expanding, but is also getting smaller and smaller. As of now, the Arrowverse Multiverse includes Arrow, The Flash (2014), Constantine, Vixen, Legends of Tomorrow, The Flash (1990), and Supergirl. The universe is also getting bigger and bigger, but the movies are changing this.
Suicide Squad is one of the movies I want to see most this year, even more than Batman vs Superman: Dawn of Justice. But, that is mainly the part of the DC Extended Universe that's changing the Arrowverse, and these changes aren't a good thing.
Let's start with what I think is the most noticeable: Arrow's Suicide Squad and A.R.G.U.S. spoilers lie ahead for 'Arrow', even though it's been awhile.
It all started in Arrow's third season, when they chose to kill off Deadshot. Although, I do still believe he's alive, but most likely he's not. Deadshot died when he sacrificed himself a hero, and was in a huge explosion. Then, in Season 4, Amanda Waller was killed. Out of nowhere, a Shadowspire agent shot her in the head killing her instantly. It seems these choices were influenced by the upcoming Suicide Squad movie, and in my opinion, these two choices were some of the worst Arrow has made, and hopefully, we'll at least see the return of Deadshot.
It has also been revealed that Deathstroke is tied up in another DC project, so he cannot return to Arrow, for the time being. I think the two most likely options are that he is either going to be in Suicide Squad or Batman. And it's been rumored for a long time that Scott Eastwood might be playing Slade Wilson in Suicide Squad, and even though Scott Eastwood is a great actor, Manu Bennett is a better Deathstroke.
To me Slade is Oliver's archenemy, even more so than Malcolm Merlyn. And Slade still has a story to be told, because, well, after all, he has the famous line "I keep his promises, kid" and I believe him.
Many people, including me, loved Harley Quinn's cameo in the 16th episode of Season 2. And for a long time, Marc Guggenheim said that her inclusion was only "an Easter Egg for fans."
But back in 2015, Willa Holland, who plays Thea 'Speedy' Queen, said that they had plans for the character, but the upcoming movie axed them. I think Margot Robbie is going to be an amazing Harley Quinn, but I would rather see the character on my favorite TV show, Arrow.
Jai Courtney's Boomerang looks awesome in the new trailers for Suicide Squad, and he's one of the characters that I'm looking forward to most. But I don't think Nick Tarabay's Captain Boomerang was portrayed well. He was one lone villain against the Arrow, Flash, Arsenal, Diggle, Lyla Michaels, Felicity Smoak, Cisco Ramon, and Caitlyn Snow. The second Flash/Arrow crossover had a much better choice of a villain, Vandal Savage. I really think Captain Boomerang should be given a second chance: he is a great character, and a great story could be told with him.
I'm glad that the movies and TV shows aren't connected, but I'm not glad that Warner Bros. chose to re-cast Barry Allen for the movies. I wish they would've just chosen someone else like Jay Garrick or Wally West (even though Teddy Sears and Keiynan Lonsdale are awesome), because Grant Gustin IS Barry Allen. I'm sure Ezra Miller will do great, but I've never even heard of the guy before he was cast. Granted (see what I did there), I didn't know who Grant Gustin was before he was cast. I'm afraid that because of this movie and Warner Brothers's plans to use the character, the show may get cancelled, and that could lead to the downfall of other shows like Arrow and Legends of Tomorrow. Take a look at Ezra Miller's Flash (sort of):
Don't get me wrong, I'm very excited for the upcoming DC Extended Universe movies, and I even liked Man of Steel. But, I'm just a little more partial to the TV shows, and Arrow has been my favorite for a couple years now. I'm sure nothing will be majorly changed, but so much has been changed that it makes me worry for what lies ahead in the Arrowverse Multiverse.
I also saw a comment on an article relating to this topic, and it said that they think the DC movies and TV shows should have free reign with all of their characters. While I don't see how characters like Aquaman and Superman could be portrayed (Superman on Supergirl?), I can totally see characters like Batman, Nightwing, Cyborg, and many others on the TV shows.
