Nan always is in favor for some kind of review template but I'm rather in-between as long as it's not just a line "oh it's so great, I grew up here, you should go see it, bye" like a lot of India "reviews". As much as we want reviews this is quite crappy and useless.
1) I would concur that we should filter out those tiny reviews.
2) Those were mostly anonymous reviews from the past and those... dont work anymore... I think there is a bug @Els ;) I am not sure we count those though anyhow :D ... Key bit, anonymous reviews are bit crappy due to me.
3) Re template: I think everyone can do as they please. With long texts using subtitles can help the reader to find the key bits though...
