The blues have washed away with Justice League, for DC movies. Although it is bit inspired by Avengers:Age of Ultron, it has honored the gravity of situation, which has paid off while its execution. As Marvel has already done all those good stuff, which are being tried out by DC. May be, it is all causing the fuss which isn't helping the DCEU to grow economically and critically. I would say just watch it as another Superhero, by leaving all the fun that you had watching Marvel. I'm sure you will enjoy it :)
