Is death note a good anime? Should i watch it ?

It's only one of the best জীবন্ত ever made!
It's a great example for new people entering into the জীবন্ত community mainly because it crushes all 'stereotypes' about anime. It's an amazing psychological thriller with a great story. It's much better if আপনি avoid spoilers for it so আপনি can watch everything as a surprise.
Though there are some people who say it kinda went downhill after a certain... incident, and there's always haters too. Ugh. But I personally think it's a great জীবন্ত all the way through! Sure, I prefer the 'first part' more, but it's still worth the watch. There's a reason why it's considered a phenomenal জীবন্ত among most. But at the end of the day, it's really your choice!
Tl;dr: I really suggest আপনি do, but it's your choice in the end! 👍

Wow someone told me I should watch this anime

HELL YA DUDE! WHAT ARE আপনি WAITING FOR GOOO!!!!!!!!! ITS MIND BLOWING AND I STARTED TO প্রণয় VILLANS , পাণ্ডা AND GORE CUZ OF IT !!!!!!!!!!
SPOILER ALERT:
I'll take a potato chip... AND ATE IT !!!!!!!!!!!

Sure. It has its flaws, but it's সামগ্রিক pretty good. Though it definitely could have been better, I recommend it because of it's interesting story line and eccentric characters. Enjoy.
