Don't get me wrong, Groovy was (and likely still is) a very pleasant alternative to boilerplate laden Java, but the lack of static typing and runtime MOP magic was, in hindsight, more hindrance than help.

Agreed re: many ways to do one thing, Scala's no Python ;-) Readability is a matter of experience. From the outside looking in some Scala code may look fairly dense, but the same can be said of Haskell. Groovy wins in this department, no argument there, any Java dev can grok Groovy.
