It's not meant to be, but that is all too often what it comes across as. You can't just pick and choose massive bits and pieces of various comic book storylines, add in your own little ideas here and there, and expect it to be taken as an original product. It's not. There are massive glaring holes in the MCU from where they've ripped things right out of the comics and not bothered to explain them properly. The original content, in the movies at least, is badly written and detracts from the comic book storylines they're mostly based off of. Civil War in particular was so badly done it was almost painful to watch it, and the less said about Age of Ultron the better...
...that said, I'll admit I'm biased more than a little, because I've read the comics and can fill in the gaps of what they've missed...and see what they've tried to adapt and failed at miserably. It's probably a lot more enjoyable to watch these films without that perspective. But when I see better Marvel movies - like Deadpool, and X-Men: Days of Future Past - out there I get kinda annoyed at the direction the MCU goes in. They either need more comic book plagiarism to cover up their inadequacies, or less of it so they can make an original story with these characters free from those incumbencies. This hybrid approach just does not work...which is why the TV series are so good and the movies often aren't. SHIELD is its own thing.
So yeah, as a fan of the Infinity Gauntlet storyline, and Thanos as a character, I'm concerned their approach to it is going to make a mess of it. That it'll be a poorly paced crossover with a predictable plot that ends with the death of the villain. Again. Even with the later films they've been very formulaic in their approach...you'd never guess there is an eight year gap between Iron Man and Doctor Strange, for example.
