Thanks for an interesting and very detailed review and bits of it certainly rang bells relative to my meet with her earlier this year.
However like many others I'm struggling to see this as a negative experience as others have stated.
Just thought I'd quote the relevant bits from the Wiki guidelines for reference below to put some context to your score:
Overall Rating
The overall rule is 'Your review, your rating.'
The choice over when to give a Positive/Neutral/Negative rating is contentious. As a rule of thumb ask yourself whether you would still choose to go through exactly the same punt if you had the opportunity again. If you would not then you should probably give a negative. If you would repeat the punt, and depending on the negatives (if any), you should either give a positive or a neutral rating.
A further test is whether you will return in the future. If you would not return then you should give either a neutral or negative rating.So based on your review I can see you would not repeat the punt as it was, so that potentially warrants a negative. The bit we find hard to grasp is the fact that you say you would return "if she'll have you". Quite an odd thing to say in a negative review that no doubt Isla will have already read. Maybe you're trying not to burn bridges but if I deliver a negative it means I have no interest in seeing the girl ever again.
My personal take on a negative is that you are stating that you cannot recommend this WG to other punters due to a serious failing in one or more important areas that affect her delivery of service that are likely to be repeated for other punters.
Sure she wasn't perfect for you and she clearly tried pretty hard to give you a good time with a few areas you clearly were not happy about but that are unlikely to bother every subsequent punter, if many at all.
It also looks like you had a better time after you had a shower or have I read that wrong?
The Chemistry wasn't there for you, which I can understand. She's not for everybody, yet you say you'll go back as she has implied she will try to be more what you were looking for. I don't think you can ask any more of a girl who fails to deliver than an attempt to rectify the negatives.
I personally think a Neutral is certainly fair in the circumstances given the bits you weren't happy with. Some may even have rated it a positive.
Your decision at the end of the day though.
I'm curious once the dust has settled to see if you and Isla do indeed get back together and sort out your differences. Personally I'd be surprised if she does block you, as I think she's pretty smart and not one to give up easily. I also reckon she'd take on board your comments and perhaps try to be more what you were after.
Alternatively she may consider you too hard to please and that she's unlikely to succeed on a second attempt so it could go either way.
Good luck next time, or on your next punt with Isla.
