I didn't see anything wrong with Lundgren as He-Man in the movie, or the other cast the problem was the weak plot, not the best graphics of the time, no battlecat/cringer or Orko which was replaced by a leprechaun type character and worse decision putting it on Earth instead of Eternia and Castle Greyskull but also not changing from Prince Adam to He-Man I think what put the nail in the coffin. With the right cast, Adam changing into him, having characters like Teela, Man of Arms, Mechaneck, Orko, King Randor, Queen Marla, Battle Cat/Cringer, Skeletor (Not shiny one), Merman, beastman, EvilLyn and others would be awesome where he must defend Greyskull against Skeletor but have him as Keldor in the beginning becoming Skeletor and wanting revenge against the palace. I watched the entire series again on Netflix and I for one want to see a awesome movie based on this that has great action like 300 and Gladiator with technology and don't change characters names in the movie.
