It's a different Marvel movie. Its one that deviates from the conventional and formulaic method. The cinematography is excellent and the story is a bit laid back. The sense of urgency that the movie wants you to feel is not felt.
Want to give it 4.5/5 stars. It's a good movie that tries to go the cosmic scale and move away from a "regular superhero movie". I have no idea what made "critics" to give it 70% or 66% rating. They clearly didn't understand the concept not what it tried to do.
And good job review bombers who gave it negative scores just because of a gay kiss. You need to rethink your life choices. You can move to Saudi Arabia and Dubai where this movie is not releasing for the same reason - a kiss!!
