I didn't watch it specifically because of Leto. I was absolutely stoked each time I saw an ad for it (forgetting that Leto was in it) right up until his stupid face popped up in the trailer.

If they had somebody else, even a complete no-name actor, I would have watched it. It is impressive how effectively they pushed away their audience.

I was so excited for this movie until I saw him and knew it would be a dud

I think if you recast everything let has been in all of those movies would have been improved

Sadly he wasn't the worst part of the film. He actually fit his role pretty well. The main female lead was pretty damn wooden. I was totally expecting my feelings towards the leading roles to be reversed but I actually think you'd have a better film if she was replaced rather than Jared. And I hate him in most things. I do think however if you replaced him in blade runner 2049 it'd be a better film. Even though he fits that role really well, probably better than the one in Tron, he's still the weakest part of that film specifically.
