Hooray for Muscles!
20 May 2010 | by TheLittleSongbirdSee all my reviews

Jerry's Cousin is not my favourite Tom and Jerry cartoon, but it is really entertaining and I definitely recommend it. Tom and Jerry are both great, but the real star of the show is Muscles, Jerry's cousin. He is quite small in stature but he is so strong, and it isn't long before Tom himself gets on the wrong side of him with hilarious consequences. While the story is a little predictable, the colourful animation, fun music and wonderful visual gags more than compensate as do Muscles's threats to Tom. Overall, this is not my absolute favourite or what I consider the best, but I had a wonderful time watching this cartoon. If you love a cartoon with great visual gags especially, you have a winner with Jerry's Cousin. 9/10 Bethany Cox
