I actually liked this episode quite a bit. Though, I wonder what Seth MacFarlane's thinking when he actually has a cutaway gag to explicitly point out how predictable his own plot is.
The antics in the casino were pretty funny, especially Tim the Bear going insane at the buffet and his purposely-lame "chicken coup" crack. The segment with Cleveland's Angels was also good for a laugh, so I'm ready to call this episode a winner. At the very least, it's better than the recent FG episodes, if nothing else.
It was good for what it was. I liked the writers acknowledging what was going to happen, but still defending it somehow. Cleveland continues to run hot or cold as his character goes. He is falling into the Peter/Homer/Stan trap of getting into these situations due to being a dumb ass. I would prefer it being more naivity like the drug dealing after school kids episode. Anabel's character has developed nicely in the last few weeks which is a shock.
My prediction is that Eko is a Nigerian priest, which will somehow tie him in with the small plane Locke and Boone found, since they made a point of saying that the people on the plane were Nigerian drug-runners dressed as priests.
