The problem is that we only get that small amount of live feed plus 45 minutes of highlights and so judgments are made on that basis.
At first I didn't like Noirin and then I began to see she had a personality and enjoyed watching her, even defended her on channel 4's website (probably no longer there due to lack of balls by mods). Now I see her as a rather immature woman who gives other women a bad name. She's trying too hard and thinking too much about how the public view her and possibly because of this she is making appalling decisions.
Another option is that she placed a bet beforehand on which housemate would be romantically involved with the most housemates?
Have now gone full circle with my opinion on her.
