Since when this was aired over in the UK, the cover songs are gone and so are the Captain N parts but this show still great even without them. Mario & Luigi may have different voices (Mario isn't too bad but Luigi sounds more scared) but the voice acting is still top notch with Toad and King Koopa, oddly I found Super Show's Princess Toadstool more gentler and softer in terms of voice than the harsher Super Mario Bros 3 one. Also the Koopalings are great new characters that looked like their game counterparts (Cheatsy, Kooky and Bully are my favourites). The one part that I like is that it fits with the game; music, locations and even bits like the Doomship as well as good plots... well most of the time (the Milli Vanilli one just has some background music from Captain N and the one where Luigi is turned into a dog are my least favourites).
The only problem is that there are too many animation mistakes common ones being; Luigi turns red, Cheatsy (or Larry) turning orange, Mario switching from brown to black hair and back after the first four aired episodes (since they have Mario with black hair) and some colouring problems which are incredibly easy to spot. Plot wise it is slightly better than Super Show but worser in terms of animation. Still, the show is worth watching if you like video gaming cartoons.
