A decade ago, Marvel released their movie adaptation of "Iron Man." At the time, people didn't realize the effect it would have on pop culture. In fact, that same year DC and Warner Brothers released "The Dark Knight." It is considered by some to be one of the greatest Movies ever made. As such, it took up a lot of the comic book attention that summer.

But life, and movies, are not without their twists. "Iron Man" was still a major success and was the starting point of a sprawling franchise, the Marvel Cinematic Universe.

The "Dark Knight" trilogy has since wrapped. DC and Warner Brothers have since created their own interconnected film franchise, much like Marvel's. They've pulled it off on the television side.

Those endeavors have been largely successful, though not without problems, both in public [VIDEO] and behind the scenes [VIDEO]. Similarly, it has been complicated on the theatrical side.

The DCEU gets a bad rap from some

The first attempt at launching an expansive cinematic DC universe was 2011's "Green Lantern." It didn't go as DC and Warner Brothers had hoped it would. For the second attempt, it would start with a new Superman movie. Comic book adaptation veteran Zack Snyder and his wife, Deborah, were hired. Christopher Nolan, his wife Emma Thomas, Charles Roven, and David S. Goyer were also brought in. The latter four were a major part of the creative force behind "The Dark Knight" trilogy.

The resulting project, "Man of Steel," was one of the biggest hits of 2013 at the box office.

It also received a warm response from critics. Beginning with the two follow-ups released in 2016, things got more difficult for the franchise. "Batman v Superman: Dawn of Justice" was a big commercial success and was enjoyed by audiences, but wasn't as well-received by critics. Much of the negativity centered on Jesse Eisenberg's portrayal of Lex Luthor. A more graphic extended edition was later released on home video. This version fared better critically, but likely wouldn't have made as big of a profit with an R rating.

"Suicide Squad," the next installment, did well financially and with fans, but was largely panned by film critics. Despite often being considered the weakest link in the franchise, it would go on to win an Academy Award. "Wonder Woman," released in 2017, was a massive hit, beloved by many. A terrible tragedy befell the Snyder family during production of "Justice League." This led to a decreased role for Zack and Deborah Snyder. Some complained that the film had an uneven feel as a result.

That said, most people who've watched the movies like them, and they have been a financial success.

Plans for the future continue

Several more films are in various states of development and Comic Book Resources indicates that people are eager to join. The Snyders, along with Goyer and Roven, have remained with the franchise. However, it seems that Nolan and Thomas have departed. Yahoo reports that the studios may also be looking for a new Superman and a new Batman.

Perhaps most deserving of the blame is Warner Brothers. After all, 2006's "Superman Returns" was a major success, however, Warner Brothers decided that it wasn't good enough and opted to start over.
