About me saying how I hate this season... well, I'm kinda starting to like S5. Sure, there's some bad episodes, but even if these episodes don't posses Spongebob humour, unlike that wretched season 4, it actually sorta gave me the Spongebob feel.
This show's going downhill, but I'd say S5 is good. I liked the Blackened Sponge because Spongebob acted really funny, and he said "football!!" That part actually cracked me up! 
There's still some episodes I hate in this season. Squid Wood, Atlantis Squarepantis, and The Original Fry Cook, to name a few.
However, don't get to thinking I like S4 now, I still absolutely HATE that season.
But now I'm accustomed to this season.
I give it a 8.0; for though not having Spongebob's old humour, but still managing to be funny.
However, I still dislike Friend or Foe. It was an apalling start to this season.

. Sure, they leveled the show down with potty humor but, surprisingly, that is helping it 
. While not as good as the original three seasons, this is definetly better than season four. I rate it somewhere between 7-8, I don't know. I would rank season four as a 5.
