I really liked HF but with the small parts count (2.0/1.0) that I had for most of the sets it really didn't appeal to me so after 2.0 I stopped buying the sets and focused on buying BIONICLE online. Overall HF was okay.
Yes I know but look at this http://lego.wikia.com/wiki/Lavertus?file=Screen_Shot_2014-04-07_at_9.14.59_AM.png He has a piece of golden chi next to him And this http://lego.wikia.com/wiki/Lavertus?file=Episode27ShadowindisalivehintImage.jpg
Remember Shadowind/Lavertus he was seemingly killed at the end of season 2 what do you think what happened to him?
Oops on the topic name I put a Z silly me!
