I think I'll rate each episode so far with an A/B/C/D scale. A being something I really enjoyed, B being something interesting but didn't quite ace it completely, C being something average which I feel didn't remotely get to the full potential of the material, and D being a turn off for me.
Note, not all A/B/C/D episodes are equal in value in my eyes, but it's a general guide as to how I feel about the episode in terms of being entertained.
Ep01 - C [Gross, gross, really gross. Ick!]
Ep02 - B [Fast paced, action packed, lacked soul.]
Ep03 - D [Terrible pacing, not funny, kinda stupid.]
Ep04 - C [Not as funny as it could be, felt a bit repetitive after a while.]
Ep05 - A [Great pacing, tight writing, solid character gags.]
Ep06 - A [Most creative episode yet, there are no words.]
Ep07 - A [Best comedy episode so far, really solid pacing of jokes.]
Ep08 - C [Kinda boring, kinda stupid, not horrible though.]
Ep09 - D [Completely repulsive and disgusting. Was also stupid.]
Ep10 - B [Relatively creative, very visually interesting, but boring.]
Ep11 - A [Crazy action packed insanity.]
Ep12 - A [Solid theme with serious dedication to surpassing expectations.]
Ep13 - A [Good humor, good variety in art design, relatively relaxing to watch.]
