There is a running theme with Kim Basinger characters and the sauce. Someone should look into this.
Cut out that Icelandic singing sequence (who saw that and thought "this is a good idea") and the Joker stuff (feels really shoehorned in) and this is close to a perfect popcorn experience. These fools missed a good opportunity the first time out. Finish this version, cut it in half, and release two movies. Alas, all's well that ends well. We got the movie that Mr. Synder intended, viewed on my phone, also as he surely intended.
