Yeah I actually think it is, SpongeBob in my opinion has had some better episodes lately in seasons 6 and 7, it's nowhere near as gruesome and poor as season 5 was, which to me was SpongeBob's worst season. Some of these new episodes I think are very good, but a lot of season 1-3 episodes and the movie are still the best, those episodes were all awesome and pure gold.
But recently there has been some shining good episodes, from The Patty Caper and Porous Pockets, to Ditchin', to GrandPappy the Pirate and Toy Store of Doom.
