Rogue One - The Force is Not With This One

I had looked forward to "Rogue One" for months and wanted to love it. I did not.
This film takes place just before the first Star Wars movie. It describes in graphically violent and depressing detail just how costly getting those Death Star blueprints were, the ones that Princess Leia uploads into R2-D2 as Darth Vader is boarding her ship.
One expects a lot from a Star Wars movie - humor, pathos, mythic narrative, memorable characters. ... Rogue One had one memorable character - K-250, a robot played by Alan Tudyk, who had *all* the best lines and was the sole source of humor. Note to filmmakers: When your robot character is more fleshed out than your many human ones, you might to flag down a script doctor, STAT.
Yes, "Rogue One" had the required Strong Female Lead - Jyn Erso, played by Felicity Jones. Sadly, Jyn is no Princess Leia, though the two do share daddy issues. The one unintentionally poignant moment came near the movie's end when Princess Leia makes a cameo and the whole theater seemed to take a moment to moan Carrie Fisher.
The lead human male character, Cassian Andor, played by Diego Luna, seemed rather hapless, as if he was little more  K-250's sidekick rather than a captain in the Rebel Alliance. Granted, it would be hard to out-hero Han Solo or Luke Skywalker, but a bit more effort toward that goal would have been appreciated.
George Lucas, the father of all things Star Wars, reportedly will head the next incarnation of this space opera epic. I expect he was horrified at what "Rogue One" did with his enterprise. I hope the Force is with him. He will need it.
