Jason Bell states "I was wondering how long it would take before the Groovy bashing would start".
Elliotte Rusty Harold also had some thoughts, and James responded to them too.
Whenever a new language comes a long a group of people come out and say "it sucks. I hate [insert feature here] about it!".
Groovy may not be your bag baybee. That's all cool :)
You like Python? Great... it is a very nice language. Ruby? Perl? Java? ditto.
Noone is coming to take away your toy, or force you into using something :)
I personally think that there is value to Groovy. I like the way that I can use it as Glue technology. I don't think that the rigid static typing way is for me on all projects (or part of projects) and I like how I can switch between a .java and a .groovy.
I prefer looking at my ant scripts in Groovy syntax (if they get complicated and I need to do iteration, or anything in the slightest programming-ish, then I want to get away from build.xml). I like Groovy Swing/SWT for putting together GUIs easily. I like unit testing with Groovy. I like using WebWork Actions with Groovy. I like writing scripts that reuse my core Java business logic with Groovy. Etc. Etc. Etc.
It doesn't save the world. There are other great languages. Use what you feel most connected with!
