I saw the teaser... a few things:
1. nice f/x, that has re-watch value enough to make it worth $1000/ticket, makes up for everything else...
2. little storyline was told, so what's being hidden and why?
3. will Han be reflected as original "Only one shooting" Han, Special Edition "Shot Second" Han, or - help us all - some alternate variant that works just as poorly as Special Edition Han had.
4. What's shown of Han, with any dialogue, seems a bit wet; was he a smuggler infiltrating in the clip or something else?
5. Hope they keep enough continuity; by now (much less 1997) there will be inevitable rough edges (Lando's ship, Han gets it somehow and roughs it up... maybe keeps it for a couple decades since we've never seen it so peroxide-white before...)
May 2018 - that was fast given the production problems... at least they fired the original directors trying to make an outright comedy out of it - what were they thinking... Then again, Ron Howard, guy who butchered and sanitized the very first "bio-pic", aka "A Beautiful Mind", is directing this thing so who knows how Han's alleged youth will be shown, assuming anyone asked.
