I just think this "melodic death" stuff is such a cop-out. It's neither one thing nor the other and is isn't good enough at either thing to add up to a coherent whole.
Generally speaking the drum and guitar talent in these bands is completely wasted.
Megadeth I've seen once. Love the band, but their show was incredibly boring. Mostly because they don't actually have one. I'm giving them another chance in February at a better venue. If they're dull again then I won't see them anymore.
