Then let him pass though by never watching it.

Too late, Decade was the first and currently the only Rider series that I've ever finished... and I love every minute of it.

Good for you. I can't stop someone from liking something. You could come to me saying that Tattooed Teenage Alien Fighters is your favorite Toku show, and all I can do is give you a thumbs up.
Now, where I raise my voice is perception of quality. Even then, I can't take your word or opinion on things because you outright said you've yet to finish any other Rider series.

Well that's mainly because I'm a newer fan, I'm almost done W and I'm watching Wizard weekly.

I'm not lying. I'm really enjoying it. Especially now I'm on Den-O. Stupid funny Momotaros

I actually have to disagree. Decade is a show that should be at least sampled to understand why it's awful. I just don't recommend it for beginners because beginners won't know better.

You watch All Riders vs. Dai-Shocker before the last episode. Also, begin watching W during the last fourteen episodes or so. That way, you can watch Movie War 2010 and not spoil plot points in W.

But it's commonly perceived as a beginner series, letting newcomers dip their toes in the waters of multiple series without having to download episodes from 10 different shows.

That's where Decade fails the hardest, imo. To newcomers, it looks like a good starting place, but it's not. It's really not.

hey i will say here my first kamen rider was decade and i orginally was not planing on getting in to the bugman but after i fifnshed watching shinkenger i said to my self that i did not finish shinkenger due to there involvement in Decade so i download thoes 2 episodes with the shinknegers in watched it then i saww preview black RX episode and went right i going to watch 4 episodeds and then became hooked on decade and now i love kamen rider.
