Masha and the Bear is my favorite cartoon of all time.
A 7.4 by the IMDb is acceptable. If I worked there then I would've rated it higher, but a lot of shows can't achieve a rating that high.
This cartoon is funnier than Mr. Bean, Tom and Jerry, The Pink Panther, and almost any other comedy show. People are just always afraid of their kids being desensitized to Masha, but this is not always the case. Masha is indeed a funny, and an "intelligent" girl (Time to Ride my Little Pony showed off her unreal chess skills when she was beating experienced animals with just a knight)
IMDb had a lot of cartoons rater higher than a 7.4, but I would rate it at least an 8.5
