I'm in love with Jesus and proud of it!
I like campaign in Halo, just not Reach's.
I powered my way through H3's on Legendary in about 4 days. It was a lot of fun and at the end I felt like such a boss, especially after I found all the skulls.
With Reach it felt like a chore, and it took me over a month just to beat it on Normal because it wasn't fun or exciting. It didn't suck, there was just no "WOW" factor at all. The levels were all bland, boring and linear. Beating it on Legendary took even longer because I found myself taking frequent breaks. The AI on Legendary isn't even good... they have God-like aim and insane amounts of health, and Elites dodge everything, but they're still semi-retarded. Anyone who has tricked the Sword Zealot on Winter Contingency into attacking Jorge knows what I'm talking about.
