Actually, I find that on the whole, DotM has given us some really amazing toys - arguably the best we've seen in the movie line.
For example:

+ DotM Voyager Megatron: Absolutely amazing figure and the best of the movie Megatron toys ever made - even better than the previous Leader toys and at half the RRP!

+ DotM Voyager Shockwave: A very well designed toy despite not having an Earthen alt mode.

+ DotM Commander Class Powerglide: A neat little Scout sized figure, even if the RRP is a bit pricey.

+ DotM Commander Class Sentinel Prime: Unlike Powerglide is based on a complex movie model. It manages to work well in both modes considering its size.

I must say that I've been impressed with the DotM line as a whole. The only figures that have disappointed me so far have been Skids (epic fail of a figure) and Sideswipe (not terrible, but pretty underwhelming all the same).

Don't judge a book by it's cover -- there's more to the DotM toy line than meets the eye.
