In the context of the early conversation with Ego, that scene isn't that bad... Again, it's one of many audience roar with laughter moments which doesn't necessarily mean 'Academy Award winning cinema'
At least as far as villains go..
They didn't go the I'm Mr Obvious Bad Guy route... although like most Big Bad isn't obvious in the first 45 min films, it's still pretty predictable... When the only sign of so-called villains at that point are the Ravagers and the C-3PO people, then it has to be the newly introduced Hero-Worship character..
So no repeating Ronan at least.. For God's sake though,
Why didn't they at least do something with Thanos other than remind us that the two 'sisters' hate him so much..?? At least in the mid-credits
I thought the movie came across more as setting up the middle story of a trilogy, than it was a lead-in to Infinity Wars...
