Just viewed the extended scenes up to the end of Prohibition they really don't add much do they? The Eve stuff is probably the most interesting.
Whilst I'm glad I've seen the additional scenes, the extended version is a bit of a disappointment.
It may be slightly sharper than WB's 2011 Blu-ray, but there's a tint throughout, compression artifacts and a lowering of contrast. Ignoring notices about the restoration etc, the running time has been increased by 20 mins 38 secs only.
This is less that the 26 minutes promised and a further 20 mins 22 secs needs to be added to bring it closer to Leone's 270 min version. I can only hope that one day a better version which addresses some of the shortcomings will be released.
