A nice Comicvine article about why WB shouldn't start with the solo movies.http://www.comicvine.com/news/why-a-justice-league-movie-should-come-out-first/145843/
A team film first strategy can be done, but I don't necessarily agree with his reasons to why it should be done.
His main reason to throw it out seems to be based on people's interest of the lesser characters not being enough.
He never mentions Thor or Captain America.
He also didn't give the whole picture as to why Marvel's build up strategy was so successful.
They understood not to make Thor and Cap over-budgeted nightmares of movies like Green Lantern, and despite not pouring huge funds into it Marvel still gave quality films to us that let us get a look at the characters and why we should root and care for them.
It's easy to say DC shouldn't follow the same footsteps as Marvel but instead of going against the flow of something successful just for the sake of being different people instead need to look at why the avenger's were so good cause of the solo movie first stratagem and figure out how those things can translate it into a team movie for JLA first approach.
For instance it was easy to root for Cap and Thor after their solo movies, but with a team movie first approach it could be hard for them to build up that character equity so they should probably pick a villain that will not cause the audience to root for them instead of the heroes.
