Apart from a few moments (the introduction of the two dice players, for example) I don't find ROTM all that silly or awkward. Also, they got much better in the lyrics department since the 90's/reunion, imho. Well, except for Bruce. I know a lot of people love his lyrics, but I'd much rather listen to clunky silly stuff like ATG or Where Eagles Dare or even Weekend Warrior than to hear either his silly mysticisms (though he actually got better with time, the solo career and SSOASS being his worst offenders) or his "poetic" stuff that sometimes sounds cool, but has no discernable meaning at all while taking itself way too seriously (Starblind, If Eternity Should Fail). At least make it completely nonsensical and enjoy the phonetics (like Cocteau Twins) and don't sound more stoned than the entire crew of Grateful Dead (I mean, if China Cat Sunflower could be mistaken for your work, you're in trouble). That said, Empire of the Clouds is (lyrics-wise!!!) absolutely stellar and I wish he gave us more of stuff like that.
And thankfully, at least he manages to mostly avoid the sesquipedalian Epica route (Semblance of Liberty, Deter the Tyrant, Victims of Contingency, Consign to Oblivion etc., "I can see, I perceive this ain't me!"), but he's a native speaker, they're not, so I'm more critical to him.
Anyway, unless the lyrics make me do a double take (which, unfortunately, ATG, TTAL or QFF all do), I can happily ignore them. Oh, and climbing like monkeys, but that's expected.
Edge of Darkness is actually - funnily enough - right on the edge, it manages to quote the source material directly and it is a bit shoehorned, but I think it works ("Here I am the knife in my hand // And now I understand why the genius must die")
