I definitely like them. However, as someone else pointed out - a few of them are the same with a different title and the difficult increased slightly. I was really hoping we'd see a different and unique area for each mission.
The only crap part about them - the xp rewarded has caused my character to be at a higher level than the area which he's questing in.
I literally had to skip the Imperial NS bonus series because I was already 4 levels above the quest requirements.
