This, but the good really does outshine the bad.
Rule of thumb for Bendis's Avengers: the first two arcs of "Insert Series Here" are dynamite, rest varies. If you wanna read the creme de la creme, I'd reccomend:
Avengers Disassembled
New Avengers until it hits House of M, Civil War
First Arc of Mighty Avengers and New Avengers after CW
Secret Invasion
Dark Avengers
Siege
First Two Arcs of Heroic Age's Avengers\New Avengers
AvX
