Sanctuary was a Sci-Fi web series that was picked up as a full show, so it is not unprecedented. Highly unlikely though.
Quite right, I'm sorry.
Still, Sanctuary started out as a webisode series intended as a backdoor pilot...it wasn't demoted from an hour TV pilot.
...Blood & Chrome *had* a rough-cut pilot, and it didn't instill confidence in the network.
For the record, non-reality based scripted original programming SyFy Channel still produces are now:
- Being Human (USA version)
- Eureka (final season)
- Warehouse 13
Still, given how fluffy their line-up is, it's hard to say what particularly was disappointing to them. It could have been too gritty, rather than shitty.
