No, it is not. You see, the CW is known for having content that consists of teenage angst, melodrama, bad writing, bad acting, and filler. These qualities makes up Arrow, The Flash, Supergirl, and Legends of Tomorrow. The acting ranges from terrible to sub par. Many of the actors are just hired mostly for their looks while their acting ability usually comes second. Most of the time, the writing is mediocre when its at its best, due to the writers not being up to the task and are limited by the restrictions put on to them by the network. These restrictions are that they should insert many forced romances, melodrama, and concentrated amounts of teenage angst. Many times, the adults on these shows act more like emotional teenagers than grown adults. The whole Oliver and Felicity romance is just terrible and Felicy herself has become so prominent that people have began to refer to the show as "Felicity and Friends". Makes a ton of sense. Seriously, the CW is specifically aimed at teenage girls (and my mom).
The CW can never catch up to the likes of HBO, FX, AMC, and Showtime. The shows on those networks tend to be of much higher quality and are critically acclaimed. Shows like Breaking Bad and the Wire will be remembered as being some of the greats. Arrow, Flash, Supergirl, and LoT will not. They will be forgotten like Smallville. Like its demographic, only the teenage girls will remember these shows. Not my mom, she'll forget them with age. Just kidding, I love my mom. You see, as with any show that runs for too long such as Supernatural and Smallville, the "quality" decides to diminish as time goes on. There are people like Armin from ComicBookCast who actually think Smallville was an awesome show.
24 episode seasons are a bad idea. Due to the large amount, there tends to be a lot of filler that doesn't advance the story and just wastes everyone's time. It even starts to drag on and on and makes the viewer become disinterested. A show that has at most 13 episodes should do just fine and flow much better. Quality over quantity.
Having less episodes also helps the budget. The budget would spread out more evenly and allow for better things such as better actors, better writers, better sets, better effects, etc.
Making the demographic for these shows be for teenage girls was a bad idea. I can not believe that many people actually eating this stuff up. It's mediocre, there is nothing impressive about it. I have read articles where people have said that the Flash was the greatest TV show on right now. What a bold claim. If it is the best then TV must be pretty bad in comparison. Wrong. Many shows on channels such as FX and HBO easily proves this statement as being completely false. Someone even made a list where they stated that Arrow is one of the best TV shows to watch. Big thing to stay but the opinions of the article is later called to question when they mentioned Family Guy in that list, so make of that if you will.
All in all, Arrow would have fared much better quality wise, if it had been on HBO or FX. The same thing can be said about the Flash. That way, the shows would be of higher quality in terms of storytelling and acting.
