3. Make Arrow Part Of The Universe
Seeing as DC already made a mess with similar show Smallville, they would be foolish to make the same mistakes with Arrow. The show itself demonstrates plenty of potential, and with a little polish could become a lot better. Stephan Amell has done an excellent job as the new Green Arrow, which is why I think DC should incorporate him into the Justice League of America movie, even if it's only a cameo. Hopefully by the time JLA is released, Arrow will have three seasons under its belt, so I'm sure some recognisable faces will have visited Starling City, which could open up some interesting storylines. There is no need for DC to waste money on making an expensive Green Arrow movie; they should just let one of the league's members pay a visit for the season 3 finale, which will set up Oliver Queen's role in the universe. Arrow already has the audience, so why not use it?
