The thing about "Mare-Do-Well" though is that, your favorite analyst Mr. Enter has actually said that despite its problems, he does not consider it to be one of the worst episodes in the series. Since like me, he's admitted that he found the episode entertaining overall. Which is why I feel that the absolute worst of Season 1, is worse than the bad episodes in Season 2. Because I didn't find anything redeemable in episodes like "Boast Busters", with the exception of Trixie and the ending twist.

That’s just different thoughts/opinions. There are people who can like the lesser liked episodes of the show despite it’s problems. And even the most loved episodes of the show can bit nitpicked to death. It all depends on how entertained you are throughout the episode. You can say these are Guilty Pleasure episodes. In each of the seasons my guilty pleasure episodes are the following. Season 1: Show Stoppers. Season 2: MMMystery at the Friendship Express (I think that one counts, I thought the episode was pretty funny though I think some people called bullshit about how Fluttershy, Rarity, and Rainbow all ate the cake even though they knew it was Pinkie’s mission to get it to Canterlot safely). Season 3: Keep Calm and Flutter On (I kinda say this because I have a bit of love/hate relationship with the episode xP Like far more intense then for Daring Don’t) And Season 4: Somepony to Watch Over Me which you know why from what we’ve talked about.

However I generally agree with the consensus that Mare-Do-Well and Spike at your Service are the worst episodes of their respective seasons.
