I support this petition. because the cast and storylines had a lot more potential left in them to go on for a few more years yet, and the series was excellent. TV needs more than SGU (which is ok) on its screens one night a week. SGA whilst being Sci-fi program had both comedy and drama & a brilliant cast. We need more. So please bring back Sheppard, Mackay, Lorne, Teyla, Wolsey and Ronin asap.
