It's a very solid game, with some of the most fun gameplay in the series. The story mode is also a lot of fun, though feels like it had some missed opportunities.

The biggest issues are the character models themselves are often pretty wonky, the fact that all the "comic book-ness" in 3 and prior games is hardly present in favor of trying to capitalize on the MCU, which just leaves the presentation falling a bit flat. A lot of the new roster picks are great, especially on the Capcom side, but a lot of the issues with its creative decisions can be chalked up to the Disneyfication of Marvel as a brand and it shows. Most of the roster being reused straight from MvC3 is also kind of a drag, and the lack of X-Men or Fantastic Four-related characters definitely feels off. The Marvel character themes are also all really boring and "MCU-ified" compared to Hideyuki Fukasawa's amazing soundtrack from 3.

Overall, it's a fun game, but definitely doesn't quite hit the same heights as UMvC3, with most of that being chalked up to how the Marvel brand has been handled since like 2012 or so, which is a shame.
