"Attack On Titan" is a phenomenal success as a manga and anime. But when a live-action movie adaptation was made, it got the people behind it wondering why the film has gotten bad reviews. 

The manga creator, Hajime Isayama, wanted to understand why the adaptation movie of his "Attack on Titan" manga (and anime too) has been slammed by critics, giving left and right bad reviews especially by the viewers in Japan. This news has been released by Kotaku online magazine and Yahoo! News.

If the director, writer and producer would not learn from the negative reviews that were released after the "Attack On Titan" Part 1 hit theaters on August 1, 2015 in Japan, then the part 2 of the movie adaptation will surely have the same plight.

Why was "AoT" part 1 poorly received in Japan? Why did the critics give negative reviews? Movie Pilot reports that critics and fans "have not been kind to Attack On Titan Part 1, and preview showings of Part 2 garnered a similar response."

Movie Pilot also says that both the critics and viewers have criticized the story line including the overly theatrical acting, and [of course] the "realised 3D maneuver gear."

There's no question that the plot of the "AoT" manga is very complex, exciting, gritty and thrilling-- so the aficionados gladly liked the idea of a live-action movie adaptation hoping that it would bring the plot to a more realistic level than the manga could. Unfortunately, the movie has failed to bring the "fantastic nature of the action" to life, instead it simply puts the comic into the big screen. The movie failed to deliver what it is capable of, which the manga could not materialize. As Cho Eiga Hihyo puts it, "that concept undermined the entire film, making it feel even more like an 'unrealistic' manga than the work it was based on."

Fans and critics unanimously think that the appealing aspect of the manga and anime were discharged, leaving the live-action "messy and had not been well thought out."

Having said those opinions, Tohu studios must take it into consideration if they (including Hajime Isayama) would get thumbs up from the critics and viewers. They must maximize the capability of the film and utilize the film technology. They must apply a different approach for the part 2 of the film. Isayama has previously told Yahoo! News that they had a meeting and "took into account the "various opinions" as the sequel, "Attack on Titan: End of the World," was completed."

On a different note, Pop Inquirer reports that the "Attack On Titan: End Of The World" aims to "outperform its predecessor at the box-office worldwide." It says that "AoT" part 2 would take fans back to "futuristic and apocalyptic Japan" wherein the people are trying to fix the breached wall. But aside from repairing the wall that was destroyed by titans, these gigantic humanoids continue to devour people. So the Survey Corp and the rest of the military have taken their last stand together with Eren Yeager.
