What I said in the game's comments on this site:
The singleplayer mode alternates pretty evenly between unbeliveably epic, attrociously horrible, and meh. Co-op makes it about a million times more fun, especially with 3 or 4 players online. Me and a friend of mine started playing it at 17.00 and were finished by 02.30 even thought we took an hour or so of breaks, so it's not very long either.
What the game really is about is the kickass multiplayer. I've only played it on 4 player splitscreen, but even that was so much fun I can't imagine what it would be like online. Especially for the Yanks, who appear to be required by law to demand online multiplayer in every game they play. =P
So yeah, I pretty much agree with you about the single-player mode, but multiplayer is supposed to be the point of the game. Wouldn't have minded if they had made the campaign a bit better, especially the part where you run around in the Flood's arse and try to find Cortana. Definitely way, way, way, way overhyped, but still an extremely enjoyable game.
