What? No. That kind of thing applies for NSMB, but mostly to those who refuse to see how derivative it is.
Contra 4 is a genuinely good game. Excellent graphics, animation, music, and gameplay. It just FEELS like a Contra 4, and that's fantastic.
It'll kick your ass initially, though it's actually quite balanced. It's the best kind of difficulty for a game.
You also get the NES Contra and Super C as unlockables.
