These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Ending Fatigue: The season 8 finale. The boys get arrested... then there's still ten minutes worth of wrap-up. It makes Lord of the Rings feel like a blink and you'll miss it moment,
Ensemble Darkhorse: Conky - More likely Bubbles himself, as he became easily the most beloved character on the show.
Bubbles started off as a minor character (the actor who plays him is a producer/writer of the show). By the fourth season he's not only main cast but a full-on lead along with Ricky and Julian. Conky could be said to have a bit of a Broken Base, while some absolutely loved him, others truly hated the puppet for various reasons.
Idiot Plot: The majority of the time, the plots are rather far fetched and silly, but they're still practical to the situation they're facing. Season 7 just takes it a little far when they decide to build a track for a toy train to transport their drugs over the border to the USA. There are literally dozens of ways they could have made this easier, like simply filling a garbage bag, going into the woods, and throwing it across the border at night time. The fact that their 'henchmen' were able to spend enough time there to make the track without getting caught just proves they could have pulled it off that way.
Nightmare Fuel: Conky again. Played for laughs with the ominous music that accompanies him, but the viewer is never quite sure whether Bubbles is in control of him.
Seasonal Rot: Season 7 is largely considered to be roughly on the same level as the others, but some parts of the fanbase dislike it due to the wackier plot and the return of Conky (see Idiot Plot above).
In Season 8, the plots are a little less silly, more in-line with seasons before 7. The character traits are more exaggerated than ever, which is good, bad, or indifferent depending on who you ask.
