Many Marvel fans were disappointed by the first trailer for Marvel's Inhumans, but they certainly weren't alone. Even Roel Reine, who directed the first two episodes of the upcoming drama, was less than impressed with what he saw.

"When I watched the first trailer I was like 'ooosh,'" he told Metro. "But me as a filmmaker, as a director, you’re not involved with the marketing part of these things," he said. "The trailer was made by other people, so I was really nervous about it when I saw it. So I was like, 'Oh, guys,maybe we should hold off,' but it was too late because it was already in the open."

Some of the complaints were directed at the effects shots, the costumes, and the scenes set in the lunar city of Attilan. However, Reine suggested there was still work to be done on the final product. "I felt like it didn't give you the scope, it didn't give you a lot of secrets or visual effects," he said. "I felt it was a little bit too early because the visual effects were not ready – Medusa's hair was not ready. So I was really nervous about it and would think the fans would not really like it."

The recent Comic-Con International trailer, however, featured more polished effects, including Medusa's prehensile hair and the teleporting Lockjaw, all elements that were better received by fans.

The first two episode of Inhumans will premiere Sept. 1 in IMAX theaters, followed by their broadcast debut Friday, Sept. 29, at 8 p.m. ET/PT on ABC. The drama stars Anson Mount as Black Bolt, Iwan Rheon as Maximus the Mad, Serinda Swan as Queen Medusa, Ken Leung as Karnak, Isabelle Cornish as Crystal, Eme Ikwuakor as Gorgon, Mike Moh as Triton and Sonya Balmores as Auran.
