Same story as Musa
I'm not entirely sure which script was written first (I would assume it was Musa since it came out a few years earlier), so did Heaven and Earth rip that story, or is it even based on the same script? These stories are so similar it's almost the same movie.
For my money though, Musa was far better, I would recommend seeing it for anyone who has seen Heaven and Earth. It's relatively unknown, comparatively speaking (despite being one of the biggest budget movies to come out of Korea).
I also thought the magic element in Heaven and Earth was a little forced.
