The sidekick, by far one of the worst ideas in comic book history (face it, if the only thing standing between you and death at The Jokers hands is a preadolescent trick or treater, youre in the wrong line of work), Marvel pointed this out by not really going there for the majority of their heroes with one exception. Captain America came from that early era, and had a then obligatory side kick, Bucky Barnes. Even though Marvel wisely killed Bucky retroactively upon Caps resurrection in The Mighty Avengers #4, they then decided that Cap (A one man army) wouldnt be Cap without a plus one (One manderp?). After trying out Rick Jones for a while eventually they nailed it (by nailed I mean they really screwed up) by creating The Falcon, leading candidate for the most useless superhero ever. This is actually a good thing in terms of making a film. Consider that the higher the expectations the higher the likelihood for failure, so if no one expects The Falcon to be good, anything of note will be considered a success. Remember, the X-Men Empire was built on low expectations. With that being said all we need is a story that plays to the issues best suited for a character that is well, god awful. The trouble is Marvel took the first African American superhero, made him lame and then decided even that wasnt enough. In 1975 Steve Englehart figured, what good did it do for readers to have a positive black role model in their comics, when it would be way more awesome to play to base stereotypes. So, in order to make Falcon more interesting he was retconned from being a social worker to a thug with mob ties and of course a pimp, way to go Marvel. The film should run with this and make it a redemption story where SHIELD steps in and offers Falcon a chance to change his life. The Watchdogs would be perfect villains due to their white supremacist ties. The movie could end with whatever lead in they use to introduce Falcon in Captain America: Winter Soldier.
