Riding on coattails of The Lego Movie's success, The Simpsons offered a brick-style Springfield and a plot pretty blatantly stolen from the aforementioned movie this week.

But it's not like they don't know it. And expect the audience to criticize it.  I mean, Homer's first line is: "It's not selling out. It's co-branding. Co-branding!"

And while The Simpsons Season 25 Episode 20 may feel like a retread of a popular film, the show utilized the recycled plot in a inventive and heartwarming way.

It seems like the series has been a little fixated on the Homer-Lisa relationship. Two installment this season - The Simpsons Season 25 Episode 16 and The Simpsons Season 25 Episode 17 - focused on the sweet, and yet sometimes frustrating, bond between the father and daughter.

While both of those episodes seemed to use the relationship as convenient plot device, I felt like this one really delved into the realities of father-daughter connections.

Lisa is growing up (all evidence to the contrary), and Homer has to deal with the fact that his daughter will outgrow playtime with Dad. And once she has a bunch of older friends who actually want to hang out with her, Lisa starts to distance herself from Homer just when they really started to get along.

So, how does Homer deal with the devastating emotional experience? He creates an entire alternate reality in his head "where everything fits together and no one gets hurt."

Sure, makes sense.

And it actually really does. Especially Homer's reluctance to return to reality and eventual realize the importance of growing up and moving on. All in all, it was a pretty successful episode with a really relevant lesson.

Plus, the Lego world of The Simpsons was a real treat to see. Bart destroys the school and has to rebuild it, which leads him to discover a talent for mixing and matching play sets using his imagination.

Characters are destroyed left and right, as well as police helicopters; but everything can be easily put back together or stored until they have time to rebuild it.
