Watchmojo is a popular youtube channel that has uploaded thousands of top 10 lists throughout the years. They are still churning them out about a dozen a day. You'd think with how many they upload, that the quality would be shoddy at best, but their lists are actually surprisingly well-researched and are competently voiced. I consider myself a bit of a sports buff, and I was surprised at how good their sports lists were, I was expecting much worse from such an infamous youtube channel. There are certainly much worse youtube channels out there than Watchmojo.
It's not all good though, the editing is pretty much the same in every video and that can get a bit repetitive after a while. They also have some really infamous lists such as putting Gravity Falls in their top 10 worst Disney shows list (still don't know how that happened). But, most of their lists are actually pretty decent, it's just the outliers that people like to cherrypick to prove how watchmojo is bad when they're really not.
VERDICT: 6/10 (Decent, definitely not bad)
