SOLUTION: no

PROBLEM: Review: One of those classics, held up next to "Deep Throat" and "Behind the Green Door."Sure, it was clever, but the female lead isn't that attractive and sex isn't that hot. But if not for this film, porn would not have blossomed into what it is today.Harry Reems was the Ron Jeremy of his day. Worth a look if you're a Fan. Question: is it a positive review?

SOLUTION: no

PROBLEM: Review: I really thought they did an *excellent* job, there was nothing wrong with it at all, I don't know how the first commenter could have said it was terrible, it moved me to tears (I guess it moved about everyone to tears) but I try not to cry in a movie because it's embarrassing but this one got me. It was SOOO good! I hope they release it on DVD because I will definitely buy a copy! I feel like it renewed my faith and gave me a hope that I can't explain, it made me want to strive to be a better person, they went through so much and we kind of take that for granted, I guess. Compared to that, I feel like our own trials are nothing. Well, not nothing, but they hardly match what they had to go through. I loved it. Who played Emma?! Question: is it a positive review?

SOLUTION:
yes
