My biggest and main problem with the setup of this episode is this: if the team purposefully went out to capture a wraith, wouldn't they have an even better plan of rehabbing the wraith into a human without exposing as much of Atlantis or anything like that as possible? I would have expected that much more precaution would have been taken.
Even if you do the treatment in Atlantis, shipped the guy out to an alpha site for rehabilitation (ok, I know the Atlantis alpha site is quite primitive and not really suitable for this but if this entire experiment was initiated by the Atlantis team, rather than just a coincidence of capturing a wraith, you would expect the team to be much better prepared).
Another thing, I kept on expecting the team to do something quite compassionate and human that may have a lasting effect on Michael but I never saw that. Teyla's speech may had supposed to serve this purpose but it fall flat, in my opinion, in stressing the main difference between human and wraiths...the obvious thing about human is not constraint by the constant desire to feed like the wraith.
