Pixar is great, we all love Pixar. But their past several trailers have all started with a long vanity reel: "Over the years..."
If there is one studio that needs no introduction, it is Pixar. They could flash the company logo and Luxo at the start and go straight into the trailer and people would be sufficiently thrilled for a new Pixar production. There's a hint of flashing the bling with their intro reels that seems unnecessary.
