I don't know if some of you deserve this. As naturally, I would move on from the fact that you are ignorant. But the fact that you find yourself here and appreciate a very open minded genre of music, I will give you guys this.
I've read through a few people's comments and it's all the same. You won't like Opeth if you don't have patience, and if you don't give them a chance.
You can't listen to them for 30 seconds and determine if you like the song or not.
You can't listen to the song once and determine whether you like it or not.
The problem with them is, and why most people don't like them is...
Their songs are too powerful and have too much meaning. They also change your emotions while you listen to them. One second you are ANGRY and READY TO KICK SOME ASS. Next second you are relaxed, and a lover. People, in general, don't like other people controlling them... PLAIN and SIMPLE.
When you listen to music, you are allowing a band to take control of you, whether you are aware of it or not is up to you.
Not only is the artist filling your mind with words and connecting you on some level or another. The music is also telling you how to feel.
With powerful bands like Opeth, that can really take control of you from the inside and open you up to a whole new world. People instinctively, don't want that. They don't want to be taken control of. So the result is them brushing it off as "boring" or "predictable". Meanwhile, they go back and listen to their music, which could also fall under anything you call Opeth.
Any, and EVERY band has a message. Whether or not you can grasp it is completely subjective. To grasp a band like "In Flames" can be quite simple, but at the same time, quite hard. It's quite simple, because if you are ignorant, you can connect to them on some level. If you are intellectual, you can connect to them on another level. A band like Opeth, doesn't really ever give the ignorant a chance, strictly based on the length of their songs. If you are ignorant, you will not like Opeth. Which can be said about anyone, who doesn't like any band. They are ignorant, if they assume they understand their message, and move on, without actually giving it a chance.
To assume you have even come close to figuring out what Opeth is, what they do, and how powerful they actually are, is only hurting yourself. This band, as I have experienced first hand, will open your minds if you let them into it. If you allow yourself to listen to their full length songs, more than once, and consume them, until they are a part of you. You will see what they can do to your mind and eyes. How they can open you up, and connect you with mother nature, and a whole new side of yourself that deals with human nature. They truly are , one of the most powerful bands, I have ever listened to. You should really give them a chance.
*NOTE*
If you say they are boring, its just an excuse, it is a form of you blaming them for your inability to appreciate something that is so foreign to people these days. Patience.
