Reviewing a second preview? Even with my distain for the cheap side of the industry, previews are previews, up until 'Press Night' the show is 'under construction'. If you really must slag a show off, at least have the decency to wait until it's open.

My view is that waiting until after press night to review a show went out shortly after husbands thought it was their right for wives to have their dinner on the table when they got home! Times-they-are-a-changin', and that includes the reporting of news and reviews. Just as the advent of television killed off British Movietone News, so the internet is having a major impact on reporting. I am not saying this is good or bad - it just is.
The industry itself is no longer in thrall to the gentlemans agreement of waiting until press night. Many national papers print reviews based on a performance other than the official night. Or even in Sheridan Morleys case performances seen earlier in another country!
The practise of "half-price previews" has largely vanished from the West End - if audiences are being charged full, or near full, price they should expect a finished (or near finished) production. In the case of Can't Smile at Bromley the tickets for the first couple of performances are reduced by a measly £1 on the cheapest seats upto a maximum of £6 on the most expensive - even the best seats have less than a 20% reduction.
Nobody, not least the producers, ever complains when a 5* rave is published based on a preview - it is only when fault is found that they rush to defend the work-in-progress. Yet as we have seen recently (Gone With The Wind / Behind the Iron Mask anyone) there are aspects of some shows that no amount of fine-tuning is going to improve.
Shows have always been tinkered with post press night, but we have also seen in more recent times major productions being closed for a short time to allow for major re-writes many months into the run. Does that process negate every review written from the original press night?
It is beholden on a reviewer to make readers aware that the review is based on a preview, but I can see no valid reason for withholding the review until a certain date of the producers choosing (often nothing to do with when a show is "ready" but when it will not clash with other more newsworthy events).
Mind you - if reviews follows the trend of television news we will shortly be getting reviews starting "Critics are expected to reveal that the show is...." the day
before the first preview!!
