SG:U has a go!! tho i dont like the sound of the plot too much, sounds stupid!
Yeah, some SciFi Channel guy, named Howe, said that they wanted to target SG-U at a younger population, by using younger characters and making it more "dramatic" (space opera ala "Battlestar Galactica", which BTW, some of my friends said they loved it because there was a lot of sex and hot girls, lol). This "younger" thing reminds me of episode 200th of SG1, of the "teen SG1" gag. That can't be good.
About Season 5 finale, Joe Mallozzi says that the season won't end in cliffhanger, but still they'll do the movie.
Cheers
