I think Spartan Ops is a bare bones mode and was lazily put together. The episode cutscenes are cool, but the missions themselves are so lame. It's the same 5 or 6 maps, with just different enemies and buttons to push with a cheap plot device shoe horned in there to make it seem like there's some kind of plot for that mission.
I know there will be new maps in Season 2 of SO, but it'll probably still be the same formula for missions.
I honestly would have preferred a more fleshed out Firefight mode.
