This is not one of my favourite episodes. I've only seen it twice. The first time was OK because it was new to me. The second time I didn't enjoy it at all but I can't put my finger on why. The acting was mostly OK, particularly Daniel as an addict and going through withdrawal. The story was OK, although I don't think the sarcophagus is solely (or even mostly) to blame for the Goa'uld being the way they are. I guess it's just going to be one of the episodes I don't watch much.
