The 1st 2 arcs (Battle of Gods, Resurrection of 'F') are generally mostly recaps of the movies. The movies are generally better (especially the Battle of Gods stuff; the movie is fantastic and the battle episodes of the saga... mostly sucks), although there are still a few great episodes (namely the more filler-heavy non-fight episodes).

The 3rd arc on (Universe 6 saga) is generally very, very good. The show really gets going in the 4th major Saga, the "Future Trunks" Saga.
