"As good as it gets"

[Barton]

Hi, I've watched the movie "As good as it gets" with Jack Nicholson and didn't really get the meaning of the title... Can you tell me what does it mean, please?

P.S.As Good as It Gets (1997) - about the movie

Things will not become any better. This is as good as it will ever be.

Thanks a lot, I hope my English is not "as good as it gets"

You will be happy when it is as good as it gets- it has a positive connotation, so your English would be perfect or so near as to not make any difference.
