I'd like to see lightsaber glows put into the older films too.

The de-aging tech on Hayden Christensen could have been better, but faces can change heaps once aging wrecks havoc, and I guess the budget just wasn't there for Hayden's mug.

I'm always amazed how different Alec Baldwin looks now to when he was younger. Middle aged men's faces tend to get significantly wider (whether it's injections or not). Weird.

One other gripe I have with face effects: the change in volume prosthetics and stuff add to a person's head often ruins the effect for me. Like Vader in full post roast make-up just looks weird. Why not hire an actor with a skinny head so the end effect will be in scale with Hayden's bonce?
