Re: Don't think it really has anything to do with the first film
It's difficult to really form an opinion of the Leto Joker since he was on screen for like four minutes total. Like a glorified cameo really. The voice he used was way too close to Ledger's. Compare this to the Phoenix Joker where I'm convinced they could have easily thrown out the entire Batman/Gotham mythology and references entirely and it could have just been about a poor looney guy who puts on clown makeup and flips out.
Leto's Joker is also in that new Zack Snyder Justice League. I, uh, don't know if I'm going to see that?
I maintain that the best description of Leto's appearance (the first pic of him released) was "Perry Farrell doing Home Alone"
