Character Development
In any of the Spider-Man movies only a couple of people develop over the show. Peter Parker goes from nerdy highschooler to a Spider-themed Superhero. His antagonist will go from good guy to bad guy, sometimes back to a good guy. His aunt will get kidnapped and give hints that she knows Pete is Spider-man. Most superhero movies will have similar characters and develop them.
But if you watch Arrow. If you watch fucking Arrow. Then you see the most ridiculous amount of character development for a superhero and his supporting cast. I'd even say the most out of any screened-superhero. For the first couple of episodes I hated Oliver Queen. I thought I had seen enough superhero movies to know that if I hated the protagonist not much would change my mind. But fuck me was I wrong. Oliver Queen is the man, he gets shit done. He has flaws and he recognizes them, and it happens over a believable length of time.
World Building
If a Superhero has more than one villain appear at a time it is often criticized as been overcrowded. The Avengers worked so well because every major character had already been introduced. In a movie the audience expects to be entertained for the whole movie, and justifiably so, the filmmakers don't have the time to flesh out every character and introduce new ones in a single movie. Whereas a television show has nothing but time to introduce characters and develop their motives and relations. Over two seasons of Arrow, Oliver Queen has fucked like 200 girls (198 more than Peter Parker) and has 50 villains (45 more than all the Movie Avengers combined).
There are so many secret societies running around in Arrow that it is hard to keep track of. Sure there are many alluded to in the Marvel Movies and some even brought to the forefront, but Arrow does a lot more with them albeit over a longer stretch of time. Movies barely scratch the surface of the source material, the first Thor barely showed any of Valhalla and over 5 Spider-Man movies we can't see anything as great as a Spider-Man Nickelodeon cartoon.
Actually Superheroes
What makes a hero a hero? How many times do you have to save the world to be considered a superhero? In the movies Tony Stark defeats a bigger Tony Stark to be considered a superhero. Spider-Man fights a Lizard-Man and is considered a superhero. Captain America defeats Red Hitler and is considered the world's first superhero. That is one guy, until the next movie. I would like to believe that in between movies these heroes are fighting other villains, but the movies keep telling us that nothing new has happened in a length of time. Spider-Man didn't gain any new enemies between the Lizard and Electro. In a television show you see the day to day lives of a superhero. And every day he is fighting some new guy with powers, or making a new friend. You see the inner workings of a superhero in a superworld.
Movies have their place. They are huge budget escapes with high stakes. Big events. Fun popcorn time. Large water coke with ice please. Deep-fried peppermint choctop. They are easy to see, you can see them with friends that barely care about the source material and every movie is different. TV shows require a lot more time and energy but the payoff is greater, even if the reward isn't equal to the time invested.
Get pumped for the Daredevil TV Show coming out.
