I haven't read Burning Bright so I'm going to submit a plea of nolo contendere there.
That said, if there were a Shadowrun movie I wouldn't want Renraku Shutdown or Bug City. Those are horror stories and I wouldn't want that to be a general audience's first introduction to the setting.
I suppose it comes down to what you feel the quintessential Shadowrun experience is, or the one that you would use to sell an outsider to the setting, but for me it's a heist. Get hired, talk to your contacts, do some legwork, make a plan, have the plan go sideways, navigate some twists along the way, then resolution. Even though they're not cyberpunk, Ronin and Sneakers are the examples I use the most when it comes to films that mirror a typical shadowrun.
I wouldn't want a over-convoluted or insular plot because you're trying to introduce a lot of world-building concepts to an audience that probably hasn't seen them combined like this before: magic, the Matrix, metahumans, megacorporations, etc. In that regard I suppose a mini-series (or a not-so-mini series) would be an even better fit. Trying to shoehorn 30+ years of setting into a 2-hour movie is probably not a surefire recipe for success. You have to pick and choose your elements without overloading your script.
As a powerfan, I would love almost any novel to make it to the screen (big or little), especially the Dirk Montgomery series, but a wiser approach might be to plant the seeds with some stories that have broad appeal before the sequels dive deeper into all of the nooks and crannies and splatbooks that we've created over the decades.
Edit: Welcome back, Mirikon. It's been a year since you were last around.
