No there is plenty of good stuff.
But techno sits in an odd position in electronic music.

It can be great when done creatively.
But also, anyone can literally make techno, just mash some percussive loops together, and wack a big kick under it.
It`s both a very complex and very simple music at the same time.

At least with some other dance music, unless you are using genre specific loops, you do have to make some effort with composition, like house or whatever.
Also production standards in techno as a whole I think are lower, overall than most genre`s.

Part of th edownside of the technology being so accessable.
