Star Gate Update

We just finished StarGate Atlantis Season 3 DVDs on Saturday night, but we were a day late, because season 4 started on Friday, but we couldn't watch it. Now we learned that season 3 leaves ya hanging, and it's not just "to be continued" it is a 3 parter, so we can't watch any of season 4 now, because we don't want to spoil anything, or watch it out of order. GRRR.
