Couple of things I noticed:
1. Ozzy would've been ousted I think even if he didn't volunteer after his actions post the challenge. Not only did he look like a bad sport, he appeared dangerous. I'm surprised he didn't get hurt in the process. Just bad and unclassy like he's been in F vs. F and his first season.
2. Coach and praying... well, I personally think forcing a person to kneel to pray is too far, but he did the right thing in giving thanks for the win and giving it to him IMHO. He does need to be careful to not go too far in his antics in this realm, but I personally didn't mind the prayer of thanks after the challenge.
And searching for the HII as a team event and morale booster? - well, little silly but it obviously worked. They seemed much more cohesive in the immunity/reward challenge.
As far as the movie - Sandler can do better, but I'm sure that for the Upolu tribe, watching any type of TV while being able to eat and sit in comfy chairs indoors in a comfy room it's worth spending the hour and a half of drivel.
And no - I'm not surprised Coach is a Sandler fan - sometimes his antics are a more sedate version of Sandler's as far as crazy comments.
