I have been very critical of modern Simpsons, so I went into this episode with relatively low expectations, but came out rather impressed! This episode features character development between Homer, Car, Lenny, and Moe and honestly I wasn't expecting to see an episode like that, let alone in recent seasons but it is a pleasant surprise here.
The synopsis is that the 4 of them pitch in for a lottery ticket, and completely wipe the board clean and win big! Carl then proceeds to obtain the lottery money only to never return. Realizing something suspicious has happened, they proceed to follow Carl to Iceland where they learn of his family history.
This is a great episode as it features a lot of character development between the 4 of them. There aren't as many jokes padded throughout this episode, but it's totally justified. I like an episode that slows down once in awhile and explores a certain characters history! There are also some really neat picturesque eye-candy scenes as they travel through Iceland, and that isn't something Simpsons is known for much either, but it is very much a pleasure to see! It has a very satisfying ending that I won't spoil here as I recommend you see this episode for yourself.
Solid 9/10 from me. More character development episodes please!
