You are never going to get presenters who everyone is happy with,at the same time not every subject matter will be to everyones taste.Springwatch is what it is,an easy watching programme,timed at a time when families can sit down and watch it together.It appeals to a wide range of people and has undoubtably got many more people involved in nature than other programmes.It is not Attenborough,it is simple and easy to watch and understand for millions,indeed,if it was Attenborough or someone of his stature it would only appeal to a small minority of people,probably those with an interest in nature already!!
