It's a great 2D Mario game and it's an actual miracle that they got it running on the NES of all things but I personally don't see how people could consider this to be the best 2D Mario game or even the best Mario game period. The idea and theme of the whole game being this show with the platforms being part of the set is really cool and creative. Levels are your typically Mario game levels but I feel like most of the levels don't take advantage of the game's gimmicks and power-ups like Super Mario World or even some of the NSMB games. The boss fights are pretty lacklustre and repetitive with only minor variations between the bosses. The artstyle I would consider to be the best out of the four NES Mario platformers, having more detail than the previous two but still keeping the simple charm of the designs. Overall it's a very good platformer with a lot of fun and creative ideas but I wouldn't say it's the very best in it's series.
