All of those defences, alike or not, are solid for Black. I'm just saying that Black can win too!
I have never played the Berlin Dfence before, (I think it dull too.) but the Pirc seems risky nowadays because of the many refutation lines against it.
The French is somewhat dull as well, but can lead to dynamic play later on if you know what you're doing.

In some lines yes, but not all, some are very sharp (winawer french, austrian attack in pirc...I could name you many other variations).
The Pirc as far as I know has never been refuted. Some lines lead to a small advantage for white, but that's how it is in every mainstream opening (The rest lead to a large advantage for white).
Yes, I too call shenanigans on the "Pirc has been refuted" bit.
Every heard of the Geller Quiet System? The line with the e5 advance simply tears right through the Pirc!
Apparently the Geller system of the pirc includes an early c3 by white, instead of Nc3.

It's basically just a more conservative classical system...and I don't see how it would pose black any extra problems.
That's not the Gellar system that's the regular classical system.
Certainly the classical is a legitimate try for an advantage for white, but it's by no means a refutation.
Too bad Spassky didnt know the refutation to the pirc when he played Fischer in 1972..... 
I have had trouble playing the Black side of this position. And that is the Geller System.
Ahh sorry you're right, I misread the openings site I was looking at. That is indeed the Gellar system of the classical pirc. 
Still, it's not a refutation and it shouldn't stop anyone from playing the pirc.
No, of course not! I have played the pirc many times in my own games. I have only found it to not work for me as much as other defenses, that's all.
If we ever play and you have white, I fully expect you to play 1.d4!
I wouldn't put the Pirc and the French in the same league as the Caro Kann or the Berlin. Heck I wouldn't even put the Caro Kann in the same league as the Berlin.
The Pirc and French are dynamic, unbalanced (and therefore risky) ways to fight for the initiative as black. The Caro-Kann is a solid, safe system to fight for positional equality. The Berlin is an immediate transposition into a queenless endgame...which makes it extremely dull.
