I recently found this article, that attempts to survey the arguments against cryonics. It only finds two arguments that don’t contain any obvious flaws:
Memory and identity are encoded in such a fragile and delicate manner that cerebral ischemia, ice formation or cryoprotectant toxicity irreversibly destroy it.
The cell repair technologies that are required for cryonics are not technically feasible.

the article link is broken. Via wayback machine I found it was redirected some time ago to http://www.evidencebasedcryonics.org/2011/03/11/the-case-against-cryonics/
