Two stinkers in a row don't make a trend, do they?

(For future reference I am talking about season 5 episodes Princess Spike and Party Pooped.)

These last two episodes were just, sheesh! The endings are fine, but the the whole crisis and setup are so transparently easy to solve and we have to suspend disbelief way beyond the bounds of even slapstick. These two shows were both written by first time writers Jayson Thiessen & Jim Miller. The former directed the Season Four episode Pinkie Pride and should perhaps have stuck to producing!
AS IF: Yak royalty would be stupid enough to go on a rampage when visiting another country (Xenophobia)
AS IF: Twilight and the mane six would stand idly by as they destroyed the interior of the castle, Applejack's barn, the Carousel Boutique, Sugarcube Corners... Neither AJ nor Rarity are wilting wall flowers. How come they all-of-a-sudden are as meek as Fluttershy on a bad hair day!
AS IF: Twilight would be dumb enough to continue providing the Yaks new venues to trash after seeing their earlier behavior!
AS IF!!!!
Maybe I'm just tired of seeing Spike and the viewers' intelligence abused.
Season 5 started so well! I just hope these two episodes have managed to compress enough stupid so that the remaining episodes can be more like the earlier part of the season.
