I’m not saying you have to include everything but the quote from the guardian was more so positive than neutral. And no you don’t have to include the FULL quote but if you are going to talk about THAT particular quote, then you should at least get enough what it was saying. Cause they didn’t say “She wasn’t duly stretched” they said “one can say she wasn’t duly stretched” they also added this part to it. 

“Knightley brings to the role fine, sculpted features, palpable intelligence and a nice mix of faux-innocence and flirtiness. Even if she doesn't always know what to do with her hands, she gives a perfectly creditable performance” 

If you want to go for neutrality then you should’ve added that part as well. I mean it’s still a neutral opinion and it still reflects the whole “Generally positive” part. Also in talks of CONTRASTING that bit, you should add MORE to the Quote Quinten Letts made in the Daily Mail. Which stated that she had the Charisma of a gold fish.

So you have the positive WITH the negative. This doesn’t take away from the neutrality. If anything it shows just how neutral the opinions were.
