boring OK, I have only watched the first episode so maybe it gets better, I sincerely hope so, but for a pilot, it failed miserably.
Bad writing, bad voice-acting, lazy animation, cliché and predictable story. The pilot fails on all counts.
Bad writing: Iron man comes across as an unlikable dick in the opening line, OK. he is supposed to be a dick, but a likable one. The plot of the episode is cliché and predictable; the dialogue is almost entirely entirely cliché one-liners, no conversations, no banter, no distinct characters, just cliché line after cliché line. To make matters worse the voice acting is incredibly bland, they don't even try to put some emotion into the lazy script. So the dialogue is boring, the characters are boring and the episode is predictable, the old mind-switch, been done a million times before, and here its not even done well.
Animation: Less bad, and more lazy. It looks faded, not exactly HD, and at times it switches to motion comic style, which jars with the rest of the episode. For a series which is supposed to bridge the movies it fails miserably' the characters look nothing like their movie counterparts and Iron Man still has the circular uni-beam. Also, there is no explanation of where the mansion came from.
Its almost like a cross between Avengers: Earth's Mightiest Heroes (a truly excellent series) and the movie. Perhaps its based on the comics, as someone who does not read comics I would not know.
