Fringe, Stargate, Stargate Atlantis (though Rodney's constant yelling gets annoying, sort of like Scott Bakula's of Enterprise; neither are great actors). Dark Matter is good too, but it ends abruptly after 3 seasons without an ending.

Fringe gets a little lame/silly when the alternate universe starts getting featured in the later seasons, but at least it does have an actual ending.

I really hate that aspect of the new TV programming models: studios don't even have the courtesy to write a few "wrap up" episodes at the end. Instead, they show a preview of the next season, then have no problem with just canceling it.
