Ok, the new episodes, to me are hit and miss. You'll get a good episode (Krabby Towers) and turn around and get something like "The Gift Of Gum". The problem with them is the writing. Most old writers are writing on different cartoons and simply, the new writers can recapture what was great about the older seasons. Older seasons had alot more humor and were less gross and repetitive.
Sure, some new episodes are cool with me. Season 4 was definately the worst, season 5 wasn't much better, and season 6 is off to a good start.
But you're not gonna get something like "Welcome to the Chum Bucket" and turn around and get something like "Frankendoodle". It's just not going to happen.
