I'm not really a fan of the '-blin' family of enemies in general, so their overuse in Skyward Sword did nothing but lower my opinion on the title, the silly redesign of the Bokoblins made matters even worse. Leaving the imp-like design standardized by the Gamecube era for the comical Bulldog design used by Moblins in the NES era (I'm not sure if it is just me, but giant bipedal Bulldogs just don't seem like a good idea for a Fantasy enemy). On that note, Skyward Sword reintroduced Moblins, my least favorite enemy in the Zelda universe by far. Like the Bokoblins, the Moblins reverted to their early designs instead of their more aesthetically pleasing design shown in The Wind Waker as well as the 2004 Twilight Princess trailer.
This resurgence in the "-blin" family of enemies was even more unwelcome due to the lack of many other types of enemies that had become staples in the Zelda Series. We were given 6 varieties of Bokoblin: Red Bokoblin, Blue Bokoblin, Bokoblin leader, Technoblin, Cursed Bokoblins, and Green Bokoblins, yet we had only encounter two varieties of the "Stal-" family (one of which functioned as a miniboss), no Darknuts(who would have been very interesting enemies in this game, even more so than their Twilight Princess counterparts) or Iron Knuckles, no Dodongos, no Helmasaurs, no Kargaroks, the list goes on. Any of these enemy varieties could have provided unique and interesting applications of combat, but instead we were given Bokoblin after Bokoblin (I need to know though, why did they decide to include Guays...).
On the topic of Combat, this was a huge part of my hatred for Bokoblins. Like most enemies in Skyward Sword, they focused almost entirely on defense, and a simple horizontal or vertical slash would be enough to put them under. The only variety of Bokoblin that could really do damage to the player if the player was paying any attention was the Technoblin, but this was due entirely to the fact that slight accidental angles put into a swing could cause the sword to be blocked, thus electrocuting the player. As for standard attacks, Bokoblins, like all enemies, gave obvious indications of their attacks, and a simple shake of the Nunchuck would not only prevent damage, but also provide an opening to slice and dice, the entire purpose of enemies in Skyward Sword felt less like having a hostile creature that you must defeat, and more like having some sort of magical barricade between you and the other side of the glorified hallways that made Skyward Sword's Hyrule that must be removed by swinging the Wii remote vertically or horizontally. At least enemies like Stalfos and Lizalfos had a variety of attack patterns that the player would have to forsee and guard against, instead of the Bokoblin's simple "hold arm back for several seconds, then swing forward" attack.
Bokoblin's were a simple, early-game enemy that acted as a teaching tool for the player, showing off Skyward Sword's directional blocking combat system. However, this teaching tool was recycled again and again for the entirety of the game without end, thus I feel the Bokoblin's completely overstayed their welcome.
