It's definitely worth a shot. I didn't like the first episode of TWD, either, but it got much better and turned me into a fan.
I will keep watching and hope it improves.
What's the timeline here? Two weeks before Rick wakes up? A month?
One of the producers said Rick was out 4-5 weeks, and the first season of Fear will be over about three weeks but won't catch up to the point that Rick wakes up. So really we're talking a few days to a week after Rick was shot in the WD's first episode.
