Heh, I just meant episode specific opinions. Rather than waiting till the end and asking for an opinion on Series 22 as a whole (which they still might do), they're saying "What did you think of episode 1?" "2?" "3?", etc. Definitely better this way, we don't have to try and remember what the early eps were like by the time we've gotten to the end of the series, and they'll be able to see which aspects of each episode worked better than others.
Maybe this is why they added so many new people to the Consumer Panel when they did, to have a larger group in place prior to the new series starting.
