Alright. I did some further looking into Sitchin's works. Found some areas where he's definitely wrong, some parts that are more iffy, and overall I still think he did a damned fine job of his research.
I suppose to a large extent I was infatuated with his works, but I still stand by them. At the very least, they're an informative read that offers different perspectives on the subject. In my opinion - he's still got a tidy sum of information right. But even the highly esteemed and adored Einstein has some things wrong, so I'll take that in stride and stand by what he's got right.
I appreciate your input, though, 'cause it did lead me to question some things that were bugging me (and most of the things that were bugging me turned out to be wrong-wrongish, truthfully) and I have a different viewpoint on the man and his works now.
I'd also like to point out that I like to read Sitchin's works for my own amusement, and I'm sure there's parts of his works that could be considered accurate, that I've misunderstood and have retold with more than a hint of inaccuracy. But what concerns me most is this:
How many people considered Einstein to be nutters before research proved him right? Every researcher's got critics, and while it's good to have counterbalancing data, it's also of note to point out that critics do not make research wrong.
