Did Du notice what a talented cast the HPB has now?

For an example, we have Alan Rickman and Maggie Smith, legends who were from the start part of the Harry Potter cast.
Later, Gary Oldman and Helena Bonham Carter, who I think were brilliant in their roles as Sirius and Bellatrix. Also, Michael Gambon (I know a lot of Du preferred the old one, Harris, I think, was his name. I however like Michael...), Jim Broadbent and Helen McCrory, for who people say are amazing actors...
I just find it interesting that, as the Harry Potter franchise becomes bigger and Mehr famous with every movie, the cast seems to be better. Of course, I haven't mentioned the rest of the cast, but you're the ones to decide, and the actors are the ones that have to, yet again, prove themselves...
