If you haven't seen the 2017 theatrical version don't, only 30 min of the film is part of Zach Snyders original version before Joss Whedon turned it into one of the worst DC movies I've ever seen besides Green Lantern. Yes the film is long as hell but your getting 3 1/2 hours of unseen footage and 30 min that's already been seen is in its original format as for dialog, music score and effects go. I could definitely watch ZSJL again and again
