I've read some reviews about the show on Google reviews that are just plain dumb and in many cases are not actual criticises of the show itself. I'll write them below. They are presented as is.
Review 1:
No Offence, But THIS SHOW WAS AWFUL!
I recommend you to not watch this as a kid, there are some adult jokes.
Why It Sucks:
Pinkie Pie's Voice is annoying in my opinion, it sounds like it's high pitched, she looks like she is gonna annoy people just for fun.
I saw too many adult jokes that scared me.
The fanbase is so cringy, and some of the Fanarts are inappropriate.
The Animation is still cool though, some of the voices can be bad.
It supposed to teach me about Friendship and Solving Problems. When I didn't get to make friends that much, I only have a few.
I got sleepy from watching these episodes and that was it.
There is a kissing scene from the Episode "A Canterlot Wedding" It was the worst adult joke ever!
Season 1 is boring, I don't know why. I prefer shows that have fight scenes.
Review 2:
too much pink and purple add red blue yellow get boys in it
Review 3:
I got really really scared. It should be rated R!
Review 4:
ITS OVER! YES NO MORE BRONIES THEY ARE EXTINCT
Have you ever read reviews of MLP that you can't take seriously?
