The main thing I don't like about the whole level is that so many people, including a dozen or so Spartans (included those form Noble) lost their lives because some mong forgot important terms such as "Close in weapons system", "Situational awareness", "Air defense" and the very basic concept of keeping your engines running during extractions and refuelling while in a 'hot zone' so you don't get caught short like the PoA did.
It could of been so much better than the book by a long shot and stick to canon, and yet it didn't and it sucked.
Who else would have prefered a full on ground assault from the Autumn while you race to get to the LZ? Escort, air cover, Covenent ships getting shot out of the sky right above your head right before a mountain explodes as the PoA fires it's mac in order to slow covenent reinforcements.
