For better or worse: the same as every other MCU

Rating: 5/10 (3 June 2018)

In linear algebra, a matrix is said to be rank deficient if one of its rows or columns can be expressed as a linear combination of the other rows or columns. In layman's terms, this particular part adds nothing new to the overall picture, it just uses information that is already present.
This happens to be the defining characteristic of Infinity War, there's nothing new here. What there is is a lot of action, a lot of CGI, and lots of bad jokes with a few okay ones tossed in the mix (exactly what Marvel has been doing for ten years).
The film makes a half decent effort to distinguish arch-villian Thanos from the rest of the baddies, and its kind of succeeds on a minimal level. But in the end, he's just another world conquering fiend who's bigger and stronger than everyone else (Steppenwolf from Justice League?) who is set off to collect some arbitrary artifacts.
Another issue is comes as a side effect of putting so many established characters in. Take Captain American for example, a character whose driven by morals, and whose films are relatively serious, and the Guardians of the Galaxy (about as serious as Looney Tunes). They've done fine on their own, but put them in the same scene and it just doesn't work.
At this point, if you're not sick and tired of Avenger's Universe, then good for you. But for the rest of us, one thing's for sure, haters are definitely going to hate this one.
(If you're not familiar with the IMDb rating formula, you should check it out. While Infinity War rests at an 8.8 at the time of this writing, it will drop reasonably over time as more casual viewers watch the film, and rate it the four or five it deserves.)
