This is why I have my players answer so many questions in character creation. I want them to put knowledge points in fluff places, and spend creation Karma on contacts and more knowledge/language skills. If during the 20(+) Questions portion yoiu tell me your character is a hugs Seattle Mariners fan, that Jules Targo is his favorite player and he wears a Targo jersey all the time during downtime, the first thing we are doing when spending your characters priorities in to put points in Mariners Knowledge, with a specialization in Jules Targo. That is before allocating skill points, stats points or spending a dime (though you
are spending 500 nuyen on jerseys, before you buy a single bullet, gun, deck, etc.) As I have pointed out
before, if your street samurai has an armorer and a street doc as his
only contacts, he has
failed at life. Additionally, he is probably going to fail at Legwork, which means he will be sitting on his hands/guarding the astral mage/decker for 75% of play time, which means he is
failing at the game.
And I encourage my players to min/max, so that they can squeeze every bit of skill points out of their allocated minimums. I know they will earn lots of nuyen and Karma during the game, as long as they survive of course. In my game, surviving is often more about prepping than killing, or running when things go pear-shaped. I do find well-rounded characters survive better. Either they have skills they need, or they know they aren't good enough to win the fight today, and so bail before death is the only option. Additionally, characters with lots of "fluffpoints" should be able to trigger things that refresh their Edge more often than fluff-challenged characters, which may allow for better survival/better success. Just a thought.
Your main point, comparing movie characters to RPG characters, is however, fatally flawed. Movie characters mostly have an emotional arc. If they have a skill arc, that is a montage-even in pop culture, nobody wants to spend their free time at the gym for
hours. (Or the most ingenious way to allow players to spend Karma during play sessions-"You must stand up and play a game of Wii-Fit, while listening to
Eye of the Tiger, while the rest of us taunt you!") Additionally, most movie characters are
post-PRIME Runners. James Bond has a 12 in more skills than dragons do, and 7's in most stats. (His GM was
most generous!) About the only thing he can't do is deck! Hell, even
young Indy is better than any starting Shadowrun character! Luke Skywalker goes from stupid farm boy to blocking blaster shots with an active magnetically-bottled
plasma torch, while blindfolded, in like an hour. (he should have died doing it! Go grab your toy light saber ((Yes, Mr. Black knows you have one)), go to your living room, blindfold yourself, and then start swinging it around. Touch yourself with it by accident? Good, you're dead. At best an amputee. Hit anything else by accident? ((Better replace that lamp before your better half/roommate gets home!)) Good, you set the room on fire, and fire on spaceships as ratty as the
Falcon usually mean you are dead.) If we are using Luke as an example, everything on Tatoine is backstory (I learned magic from an old man in the desert. He taught me to craft my own weapon foci) and escaping the Death Star is where the adventure
starts. Heck, it is a classic "you has been captured and must escape" starting adventure, very
Scourge of the Slave Lords. Luke is an Mystic adept, Han is a rigger, Chewie is a street sam, and Leia is the Face who didn't finish her backstory, only to later figure out that she is actually related to another party member. (That, or she took the Mysterious Implant quality, and her GM is super tricky). They grab the McGuffin, escape, are too stupid/new to the game to check for RFID trackers, are tracked to the Meet, and must then do a vehicle attack without their best driver, who comes back to save the day. Everything else is backstory.
