I loved the complex story. It was fascinating and could be very clever when done right. The continuity was remarkably consistent too. The thing I thought they did really well was to balance the side stories with the main story of the year. So in 09 for example, we had all the focus on the Glatorians, Agori and Mata Nui but at the same time we were told about what was going on in Teridax's regime. Getting that balance right is key to not making the story too complex as it allowed causal followers to know what was going on while still giving the fans the opportunity to delve deeper. So, no I thought it wasn't too complicated, but that they played it very well.
