Just finished watching this with my wife. I had seen the TC without her, and thought is was a horrendous mess of a movie...a 2/5 for me.
The TC was a chopped up mess of scenes that had no sequence to them, people doing shit for no apparent reason, and, really, was so disjointed that the oppressive tone of everything had nothing to stand on, so it just brought everything down.
This cut....WOW. Holy shit, I have never seen a movie improve so much with a director's cut as this did. There was so much necessary world-building, so much groundwork that needed to be laid to show character's motivation, so many threads were properly tied together, and, holy fuck, they made Luthor's plan understandable! The dour, heartless feeling the movie has was given support, fixing one of the biggest problems with the film.
Yeah, after watching this, both my wife and I thought it was a great, solid movie. There are still some problems (Lois running back for the spear, "Martha!", it's uninhabited, and Lex) but the movie is definitely now a 4/5, one I'd easily recommend to others.
