Why are there so many positive reviews of this movie ?

Rating: 4/10 (1 March 2018)

I watched the movie last night. I have not written a review for a long time but i just wanted to help out my friends here who might be misguided by all the positive reviews here. I love all Marvel movies, they are not Oscar winners but my expectation is to be entertained and the most important ingredients have been

Literally "out of this world" action!
Outstanding effects
Well placed humor ( one liners and all - Best example Thor - Ragnarok)
Overall entertainment

This movie fails on all this. Its a dragged storyline, banal dialogues e.g. a fight scene, someone seems to be hurt and the dialogues go like "Hw are youuuu" "I am good, and you" "I am good too" "Let's go". Taken straight from a "Learn English conversation in 5 minutes" Chapter I
Okay special effects, nothing special,lets say 20 percent of normal Marvel extravaganzas.
The story line is weak and goes round and round and round...
No menacing bad guy. The potentially menacing one had a lesser role to play.
Very stupid and misplaced one liners, completely out of the blues some of them.
All in all; i am giving it a 4 , but it could be 5 or 6 if expectations are lowered but it is certainly not the Marvel that we know.
