Well GotG Vol.3 was surprisingly good. I had heard it was pretty meh from a number of people.
Sure it has it's bad points, such as Adam Warlock being pointless, but I felt the development of Peter, Gamora and gang was quite compelling viewing. Definitely better than Vol 2, which I felt was quite weak.
Also, the space scenes were impressive audibly. Volume wasn't very loud, but the bass was enough to shake my sofa. At 11pm, I wonder what my neighbours were thinking...
