SGU was terrible. It killed the StarGate universe. Two seasons with only 2 alien contacts. Horrible. No reason to even call the damn show Gate.
Not to mention the fact that with the limited gate travel they also spent almost zero time exploring the ship.
The show was just like Enterprise. Just when it might be getting somewhat interesting it was cancelled.
Unfortunate that the dismal ratings killed not only SGU but the SG1 and SGA dvds.
