Freaking amazing!!! I still can't gasp what I just saw...it was effectively moving & superbly action-packed that comes with a jaw dropping ending which may going to disappoint some moviegoers but I'm sure it'd really make sense to the true comicbook fans. Kudos to the MCU team for making it so bold & masterfully crafted. Some may find lack of concentration or character development for some of their favorite characters but as a whole it didn't bother me much, cause you can't expect each & every character of MCU to shine in their own way of glory in one single movie. Moreover, there's the sequel coming next year and that's where many possibilities lies, even changing the course of its reality!
Btw, THANOS RULES!!! Awesome character building & surely going to be one of the best superhero movie villains of all time.
