Now THIS is how you make a cartoon, I really enjoy the humor, the show is really funny with hilarious jokes, but some of them really rely on gross out humor, the biggest and worst example of this is in Horrid Henry Changes a nappy, where Henry has to change his baby cousin Vomiting Vera's diaper, she throws up everywhere and on everyone, and there's a scene where Vera flings her diaper around and poop gets everywhere in Henry's room, absolutely disgusting! But other then that, it's really funny, it's always great to see whatever antics Henry gets up to and all the situations he finds himself in, now for the characters, Henry, as you can expect, is really horrid, but in a funny way and not in an annoying way, but do you know what are annoying? Perfect Peter, his brother, he's usually annoying and snitches on Henry for the smallest things sometimes, but in the rare occasions where they work together, oh man is it a treat, but what are more annoying are his parents, they clearly show favoritism towards Peter and punish Henry for extremely petty reasons. The first 3 seasons are great, but please avoid seasons 4 and 5, the show loses basically almost all of it's charm, and becomes more of a slice of life series, Henry stops being horrid, and yet everybody still treats him like menace he used to be, and that's when the show gets bad, however, season 5 is the better of the 2 due to having a couple standout episodes, I just really wish they kept multiple writers and didn't leave the executive producer to write these seasons herself, but the first 2 are really something special, season 3 is almost as good as season 2 in my opinion, and I recommend watching them!
Season 1: 8/10
Season 2: 9/10
Season 3: 7/10
Season 4: 4/10
Season 5: 6/10
Overall: 9/10
So what are you waiting for? Go watch the show! And remember to stay horrid!
