I find the new OP horrible beyound any redemption. Somehow doesn't fit the show imo (and certainly not my tastes)... and too much time spent on the crappy Lancelot activation. I liked the first, and i liked the second OP even more, but this one is 100% skippable material in my book. I highly dislike the singer's voice as well. A grand failure.
The new Ed... it is not half bad, but i think i prefered the old one. But at least it is gazzilion times better than the OP, and i am not planning on skipping this one
