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.
YMMV: Republic Of Doyle
Awesome Music: This show has it in spades, from the theme song (Great Big Sea's "Oh, Yeah") to the songs used in the episodes.
Cargo Ship: Slightly in the case of Jake and his car.
Now, er, sunk, due to it being blown up in the season three finale.
Perhaps not since Des has been able to covertly secure the remains of Jake's GTO in order to have them repaired to working condition.
Come for the X, Stay for the Y: Come for the rare portrayal of Newfoundlanders as something other than toothless idiots, and stay for the surprisingly good writing and character dynamics.
Ear Worm: The theme song. You might find yourself singing "Oh yeah-ee-yeah-ee-yeah-ee-yeah" for a while after you've seen a few episodes.
Love It or Hate It: People usually decide it's either a funny, interesting and escapist show, or an over-acted unfunny mess.
The Scrappy: Tinny (to some - also qualifies as the load). Has grown/dealt marijuana (which could have landed Jake/Malachy in serious trouble if she'd been caught), is a completely manipulative witch to Mal, Rose and Jake in the beginning (who are all honestly trying to help), blatantly uses Des, finally gets a chance to go to England and seems to have just thrown it away, etc.
Subverted a bit in that she actually did go to England, she just couldn't crack it and came back.
She also got very tsundere over Des' relationship with Chandra, eventually culminating in his breaking up with her, and is showing hints of yandere-ness.
Squick: Jake's reaction whenever Malachy and Rose start to get intimate.
