Certainly "The Sign" was the episode that comes closest to a movie, but despite the duration of almost 30 minutes as a special episode, it still remains a regular episode of the third season that like the other episodes could very well be rebroadcast on television. But at least I hope that in the fourth season they think about the biggest shortcomings absent in the previous three seasons. Now because of the cover image of the video, I have no problem repeating why Mackenzie Border Collie is 100% Bluey's future husband and father of her puppy, between them there is chemistry, they like each other and are clearly made for each other.
I think that "The Sign" is the pinnacle of Bluey and that "Surprise" is the icing on the cake, in fact if the series had ended like this I would have been satisfied.
I have to say this show is one of the best family shows I've seen so far at this point. Some how I can't help myself but to like some of the episodes because they make these moments with these characters very good and memorable to me. I know there are some that's not in my opinion but over all the good definitely out weights the bad.
