No it wasn't.
The titans for this year were freaking awesome and they really show how technical Bionicle used to be.I got Keetongu and Roodaka,and they are by far my fravourite titans from my collection (which also includes Krekka,Brutaka,Axxon,Nocturn and Icarax).
So people didn't like the dark story of 2005 but liked the 2006 one? Funny.
What's awful about the sets? As i mentioned,the titans were awesome,and so were the Visorak.We got the first playsets this year and they were freaking cool.The Toa Hordika weren't really the best,but they did a good job at looking mutated and stuff and they looked pretty cool.The Rahaga could have used some work,but they were definetely better than the voyatoran.Movie wasn't awful in my opinion,it wasn't the best of the 4 but it beats TLR.Check out this video,it really slams everyone's bad opinions about 2005.
I recommend watching the full series.It really explores Bionicle in great detail.
