This Lion King is an update using the latest animation technology, giving us a realistic animation rather than the original movies' cartoon feel. It is almost the same movie, wth very few changes from scene to scene, with some updates to be more 'modern'.
Chiwetel Ejiofor isn't as convincing as Jeremy Irons as scar for mine, but thankfully they didn't mess around with Mufasa!
Overall a good movie, although I like the shorter (30 mins!) structure of the original more (even if the animation looks a bit dated).
My kids love this movie. I bought the original on 2k & nee version on 2k+4k. My girls love both movies but have commented on how the picture looked better on the Live action. Definitely one of their favourites as is the original.
