In case you didn't already know, two bonus credit scenes were recently tacked onto the DC Justice League film. As a technique that is often used by DC rival Marvel, what's the role of the mid/end credit and is it worth the hype?

The surprise implementation of a plot-developing credit scene is kind of no longer a surprise. As mentioned, Marvel has made great use of this in films such as Iron Man, Thor and, of course, The Avengers; so much so that fans of the films almost always expect it.

It has its uses, of course. More often than not, the scenes introduce a potential new character spinoff or a nod to the next superhero film, even explaining back-plots. But now DC is trying its hand at it, and we don't know if we should be excited.

The majority of films under the DC franchise are produced by Warner Bros. and it's no secret the studio didn't get off to a good start with superhero releases Batman v. Superman and Suicide Squad. Despite the hype, the two flicks failed to make as big a box office return since The Dark Knight Rises – which was released in 2012. Even the recent Justice League feature has become a dividing line among fans.

So what about these bonus scenes? Well, without giving away too much of the plot, the first scene appears to be a teaser for a future DC Extended Universe team-up that could be interesting if pulled off well. It starts and ends with a race between two characters that we'll see in a joint feature soon. The second scene is a nod to fans and readers of the DC comics. If you're even somewhat interested in the franchise, this second teaser could be the reason that Justice League keeps some sort of traction with a potential upcoming solo movie for a new character.

Although the future of Justice League is uncertain, this newly-adopted feature could be a way for DC and Warner Bros. to stay on top in the superhero movie game.
