I'm indifferent to the title. It's not bad, maybe it's be better without the periods. I can think of some titles that would be better... Which would have also been better and appropriate for the last film.
I think the working title for The Muppets was actually The Greatest Muppet Movie Ever Made. Then they settled on The Muppets. I'm thinking The Muppets...Again could be the real title. Who knows at this point. It's not even shooting yet. We'll see.
Let's remember all the titles the last movie had before they settled on The Muppets.
It's not a guarantee at this point, it could very possibly change in the near future. I have a feeling they'll pick something better.
Although, I don't mind the current title that much. I just hope they pick something a little better than that.
