I started a contract job out of Lagos in March, and I agree that is hasn't been anywhere near as bad as I had feared. I haven't felt unsafe at all, nor have I gotten sick (yet). Yes, the traffic is horrible and a driver is a must (for me anyway), but we have a good crew house close the Sheraton and it has worked out pretty well. I wouldn't want to drive all the way from the airport to Victoria Island every day. We are careful not to expose ourselves to unnecessary risks, but overall I don't think it's that bad. Maybe it's just my location in Ikeja, but there aren't normally any sewer or trash smells. I've only been bothered by that once when I was at the airport and happened to be downwind of a burning trashpile. Actually, the people here are a bit "aromatic", so that would be my biggest complaint.
It's true that the contract is just a suggestion for both parties. It's good to have one, but there's really nothing you can do if they choose not to abide by it. It works both ways, though. If you choose to leave before the contract is up, there's not much they can do about it other than not pay you. It has taken some effort to adjust to the local business culture and ways of doing things, but the pay checks have come on time, and my employer seems to make a decent effort to ensure we're happy.
The "Welcome to Lagos" video on YouTube is pretty interesting and I'm sure is an accurate portrayal of the lives of a handful of people in Lagos. Keep in mind, however, that Lagos is huge and has vastly different neighborhoods and suburbs. It would be a mistake to think that all of Lagos is like the scenes they show on there. It would be like making a documentary of NYC and following around some homeless person scavenging for food at the dump. Yes it exists, but it's not the way everyone lives.
Basically, if you have an open mind and are adventurous, Nigeria isn't bad. Poverty is rampant, but the people I have met and worked with have all been great. I would prefer to work here and risk some petty theft rather than work in an area where I am considered an infidel and a terrorism target.
