I'm usually a prety big fan of sticking to the details of the source material, but man, MODOK really didnt translate well.
For the biggest problem with MODOK wasnt even the ridiculous look though, it was more that the whole character was just so fucking dumb. His scene with the daughter "I don't know what to be, just tell me what to be!" was so cringe. Just one of those moments you look up and go shit, I paid to see this in a theater
I don't know if there was ever a way to pull off the giant floating head thing, but this was not it.
