I have to step on his and say no. In almost all the highend video film/commercial i have done, We almost never use plugins but some library of real lens flares. Shoot on black backgrounds they are keyed stabilised and tracked on the pictures. It gives you a much better result and a real and organic feel that is really difficult to get with a plug in.
That doesn't mean you can't get something nice from a plug in but it is a hell lot of work to make it feels as good than a real element
usualy comping them in add or ever mode push the brightness to go extra white, that often helps
