Because "Star Wars" is so well known studios can make any film they want that is based on the original trilogy so long as the Star Wars tag is attached to it. It's a full-proof way to make money without guaranteeing that the quality will be there. The problem with that is there is no mystery left to anything; we are force fed explanations behind characters and stories that sometimes aren't warranted just so the studio can make a few bucks. Han Solo was such a cool, rogue character in the fight against the empire that I never really cared to know his origins, and why do you need to? He's a standalone icon in cinema who should have been left on his own and not used for a cheap plot that was ruffled together for this film.
