I thought last Friday's operetta on Sanctuary was bad. I finally turned it off about half-way through.

Earlier this evening I read some of the comments on the syfy.com forum. The singing episode did not go over too well with other viewers, either.

Sanctuary has been stumbling for a while. They seem to have lost direction and are making it up as they go.

Buffy did it best. Xena's musical episode was okay.
The explanation here was weak. They only needed to speak in a sing-song voice, not break out into song, seemingly effortlessly. And the "songs", such as they were, were terrible.

Weak episodes like that one at the very least have to move the seasonal story arc along in some significant way.
