Movie with the first ending ever

Rating: 4/10 (28 April 2018)

I guess I will be dissenting reviewer here among the many other apparent glowing reviews here.
I have watched the various Marvel movies and in particular the Avengers series released over the last 5 years. This one has got Marvel heroes and villains raining in left right and centre from the start with limited background or story to set the scene. The comedy in the face of apparent disaster seemed misplaced.
And I have to say it has probably got the most anticlimactic ending ever. I won't go into the details to avoid spoilers for those of you have not watched it yet. However i appreciate this was probably to get people to watch the next movie. But myself and the rest of the viewers in the theatre i was at today was shocked at this abrupt ending with little meaning or explanation. Was not impressed hence the 4 rating.
