All the Decepticon toy talk aside (only cause it frustrates me as well that we aren't getting them)
I finished watching the series over the weekend and was impressed with the overall ending. I do like how the team has new team members. I like all of the minicons.
Some of the Decepticons were really cool, like Steel Jaw, Fracture, Chop Shop, Underbite, Scowl, Hammerstrike, Terrorstrike, Thunderhoof & Groundpounder but most of the rest were forgettable some were just awful like Zizza, Malodor, Ped, and the worst of all Springload.
Despite some lame Decepticons getting 1 or 2 episodes I did enjoy the series and really like how the Bee team interacted and worked together.
While its not my favourite series of all time (Beast Wars is hard to beat) it will be one that I will re-watch again.
