I can deal with Leto as long as he isn't given too much free reign, the guy thinks he's some sort of top tier character actor and just comes across as barmy.
Good news on NIN handling the soundtrack, they're a very capable group and I feel that they'll deliver, whether to the degree Daft Punk did I've no idea but I'd be surprised if it isn't still great. Visuals look good judging from the trailer too, I'm cautiously optimistic so far but that might change as more is revealed.
