History YMMV / Bionicle2015

** As appropriate for a toy-line (especially one from a connecting-brick system), the major complaints aren't about changes to the plot or characterization, but the design of the toys. Specifically, Franchise/{{Lego}}'s decision to continue using the Creature & Character Building System (based on ball-and-socket skeleton-and-armor connections) that began with the ''Toys/HeroFactory'' line rather than returning to the more Technic-based pieces from the original ''Toys/{{Bionicle}}''. Many others stand by the CCBS builds, as not only is it a versatile system in its own right, the re-integration and improvement of gear-driven action features makes it a great, if not perfect way to bring back Bionicle.

** The fact that every single character thus far has been voiced by the same actor has some people rolling their eyes and others in stitches because he has very little vocal range outside of "gruff Australian[=/=]New Zealand accent", making his attempts at differentiating characters almost too obvious to take seriously. Some have said it lends itself to the feeling that the story is being told by someone like a bedtime[=/=]campfire story, but giving [[ActionGirl Gali]] that voice has been too hard to swallow even for those people.

** Let's just say Skull Scorpio isn't held in a very high regard because of his ''completely fixed'' legs, eye-searing color scheme, almost no resemblance to actual scorpions and all-around awkward design.
*** Ketar is in the same boat for similar reasons. However, unlike Scorpio, he's got posable legs.

* TheyChangedItNowItSucks: Some fans weren't too keen on the differences from the original toyline, such as the usage of the Creature & Character Building System over the Technic building system and the change of the green element from [[BlowYouAway Air]] to [[GreenThumb Jungle]].
* TheyWastedAPerfectlyGoodCharacter: [[spoiler:As a result of Lego's cancellation of Bionicle G2, Makuta was not given much screentime and very few lines of dialogue, with the Toa defeating him in mere minutes by sacrificing themselves. This was despite the wealth of theories being made about Makuta's role in the story and his relationship with Ekimu, as well as theories that Ekimu may end up being the big bad by way of plot twist or Makuta may actually be an AntiVillain this time around under the negative influence of the Mask of Ultimate Power or even Umarak being the main villain the whole time. Even worse, Makuta didn't get a model, with Lego only giving instructions on how to create Makuta from pre-existing models as a result of the cancellation and holding a contest]].

** Due to Lego's cancellation, one of the main criticisms of Journey to One was that [[spoiler:it wrapped things up too quickly. There were fans who wanted to see more characterization from the heroes and the villains and feel that it should have continued on for one more year, with the final year being set in the Shadow Realm]].
** [[spoiler: Umarak finds the fragments of the Mask of the Ultimate Power in no time at all, some feel there should be major story arcs dedicated to the Toa stopping him]].
** [[spoiler: The Toa having to sacrifice themselves to stop Makuta. We were never told exactly or given any indication why the Toa had to [[AscendToAHigherPlaneOfExistence leave Okoto and become stars]] and some feel that Ekimu should have pulled off the sacrifice instead, or the story be presented in a way that allows the Toa to think over this before the battle with Makuta, but then decide to make the sacrifice anyways, or be allowed remain on Okoto after their victory]].

* AuthorsSavingThrow:
** The 2001-2003 era was widely considered to be the franchise's heyday, which would explain why the reboot features a relatively simple plot and is set on a tribal island.
** Korgot, the Protector of Earth, being confirmed as female is seen by many as a huge step forward from the original generation's rigid mono-gender tribes.
** Some fans complained about the Toa being the only sets with names [[note]]The Protectors only got individual names in the novels; Ekimu's set only addresses him as "Mask Maker", and the Skull Grinder's name (Kulta) only appears in the Lego Magazine[[/note]]. Thankfully for them, the names of the 2016 sets show that most of the characters now have an individual name.

* ToughActToFollow: This is the revival of one of {{Toys/LEGO}}'s biggest {{Sacred Cow}}s, so comparisons were inevitable.
