Although this version has a few serious historical flaws, "Salem Witch Trials" is a relatively entertaining story. I agree that Part I was slow but I chalked that up to historical/cultural background that made Part II more believable. Two things that bothered me: (a) the trials appeared to be judged by two men from beginning to end when, in reality, a panel of several men was sent to try the accused, and (b) the scene of Rebecca Nurse in prison asserting New Age philosophy seemed out of character for this pious Puritan woman. Still, the overall story was accurate and believable.
I found this version to be more historically accurate (if less entertaining) than "The Crucible," simply because "The Crucible" relied on the premise of an affair between two major characters that most likely did not happen. (In reality, she was only eleven while he was in his sixties.)
Another thing that bothered me in both versions was the absence of Tituba's husband, John Indian. He played a relatively major role in the original trials.
