Big disappointment and boredom

Rating: 6/10 (21 November 2017)

while the main story of the film regarding the destruction of asgard and the entry of the big evil sister could make a great enjoyable film it did not cause those beeps at marvel chose to show us an irrelevant boring secondary story which existed in the film for a beep 1 hour and 30 minutes.
I'm talking about the grand master story in which also hulk was involved and that story destroyed the film for me.
the whole film run 2 hours and excluding first and last 20 minutes all the rest of the movie was how hulk was fighting thor in a kind of....kolloseum or something.
this part of the story should take plce around 10-15 minutes not more.
I don't know why marvel had that story for more than 1 hour in to the film but it was a boredom failure.
I nearly slept during those scenes and only in last 20 minutes I really enjoyed the film again but that won't save the film.
At some point they have to understand that this film was about thor....not about the avengers.
it's a thor solo film.
marvel has made so uch money they have lost it for good.
All in all this is the worst solo thor film of the three and it's a shame cause it had a great main story which unfortunately was ignored for 2/3 of the film.
Grade C+
