Next question should I watch the despecilized editions of the originals? Or can I just watch the originals as they are on DVD?
Well this a bit more complicated. 😃 I would assume most people here would suggest you to make an effort to get despecialised editions.
As you may know, there are several special editions: 1997 version, 2004 DVD version and 2011 Blu-Ray version. I actually prefer 1997 special edition to theatrical (original) release. Unfortunately 1997 SE is stuck in a very bad quality format therefore I wouldn’t recommend anyone trying to watch them in that quality.
While there are some changes in 2004 DVD edition that are annoying (to me), it is the best option I have at this movement. 2011 Blu-Ray version adds several extremely annoying changes that make it unwatchable for me. So if you decide to just go with special editions, I guess 2004 DVD version would be okay.
