I'm a new (and very late) fan to the Stargate Series... catching up on all of the shows via DVD, and bought Ark of Truth, and wow...the first thing I noticed was a lack of chemistry between the "new" team. It's also disturbing that Lt. Col Mitchell gets the lead the command when Carter has been there the longest. Also, the writer chose to divide SG1 into 3 separate units during their off world crisis. Special effects are ok, but nothing more extrordinary than what we see on the tv show. This could have been a 2parter on SciFi Channel instead.I also usually enjoy DVD commentary on a film, this was basically 90mins of the writer/director patting himself on the back about camera angles and lighting. No insight into the story or characters...perhaps because the story was weak.
