What does "We are not bad these days" mean? Has Dr Evil reformed?

"Not bad" is a word for word translation, but it loosely equates to same way you'd say "We're good these days" or even "We're doing pretty good these days."

is this even a correct english sentence please somebody help

Both sound strange and stilted. Perhaps a better translation would be We're fine there days, although the addition of "these days" is not very fluid and would imply that things had not been good and that the listener was aware of this

I would actually use 我们最近还好 more colloquially

我们这些天不错 ??

This sentence more accurately translates to "We have been alright recently." At least, that's my opinion
