I'm not surprised it's a short series but hopefully the overall series comes to a good finish. I've still got the second half of season 1 to catch up on.
I thought RID was a pretty accessible and fun cartoon, with enough in it for adult fans to enjoy as well as the kids. The Decepticon designs have a lot of puns and silliness but were very creative.
Presumably there'll be some other attempt to tie in to TF5 and it will be interesting to see the other ventures (like the Combiner Wars cartoon) come along.
