Well the good think about web design is that you can do whatever you like to use as a trend or something totally new. Material Design is not like a step by step method to do design is more like a what colors you could use and what kind of elements you can also use but without any kind or limitations and a lot of flat design. I think MD is pretty effyn good for animations and transitions inviting you to start using or use more SVG's instead of PNGs. The bad thing about using MD as your default framework or inspiration is that all sites that are 100%, 90% or 80% designed with MD as base is that pretty much everyone will look the same, with just some little changes.
