I enjoyed maybe the first 3 or 4 episodes of Flash Forward and then thought it was a mess as it was clear the writers were having trouble filling up the time in the episodes before the "flash forward" date happened and running out of storylines. But their initial idea was pretty good and the plot was certainly interesting. Unfortunately like Lost there was just no long term plans, which is funny because they were billing the show as the Lost substitute. And of course there were a lot of plot holes.
I liked Camelot. Definitely jarringly different than the original mythos, but similar enough to keep me interested...
Camelot was killed by the casting. The actor playing Arthur was so bad and so unlikable it was hard to watch. On the other hand the much less expensive UK production Merlin was very well made and the casting was generally very good except for the actress playing Gwen. Terra Nova was enjoyable but the writing was sub par.
