This film supposedly takes place over a 6 year span. That’s like, really weird. Basically like cutting Luke’s story in the OT into 1 two hour film.

Not exactly. Han Solo is an already established character. We know how he turns out because of the OT/TFA. It’s not like he’s some new character that needs more movies to grow attached to.
What it may suffer from is perhaps being bogged down in laying out details/information that we, most fans, are familiar with in order to appeal to newer viewers.
