The reconstructions of most dinosaurs are just terrible. I've found that artists do a much better job than scientists of creating realistic looking animals. The good ones are no more or less speculative than the scientist reconstructions, they just have more thought put into the coloring and how the animal may have looked as it moved about and lived its life. Here are some examples of dinosaurs as they may have actually looked by an artist named John Conway. Quite different than how they're often portrayed:
