I largely agree with the OP....and happy to see his thoughts because I thought maybe it's just me? My biggest complaints:
1. UNBELIEVABLY horrid lyrics....sophomoric, banal, paint-by-numbers tripe. This has been true of Petrucci stuff for a while (see Count of Tuscany); the fact he's the primary song-writer now just exposes it moreso.
2. Ballads are dull, uninspired stuff. I happened to buy Savatage's Streets: A Rock Opera around the same time TA came out. THere's just no comparison of the two, but what most stands out is the ballads on S:ARO is the piano melodies are terrific, ringing in your ears and progressing perfectly. The piano melodies in TA are dull, uninspired..and when combined with terrible lyrics make for really bad ballads.
3. The DRUMS: Oh my god the drums. The OP nailed it...Mangini is technically among the most skilled drummer you could find but his playing is mind-numbingly boring.
S: ARO is still in my 6-disc player on my old car....I haven't listened to TA (except for the handful of songs I rate as 4s on a 5 scale) almost at all. One of the songs came on a playlist the other day and I had zero interest in going back and listening to the rest of it.
I give DT credit for trying something ambitious, something different. They have been stuck in a rut for a while IMO. However, while the ambition was big, the execution was flawed.
OP: I think your post is definitely reasonable and worthy of a decent discussion, instead of simply calling you a troll and pushing you out.
However, I largely disagree with your main points.
Yes, the lyrics are not that great, and often state the obvious - but that is just how Dream Theater have always been. - I disagree here. Go back to ACOS or I&W, really anything from 90's and the lyrics were terrific.
Yes, the division between Acts 1 and 2 could have been a bit better - but given how monumentally ambitious a project this was, I think they did a very creditable job.
Yes, the story is a bit What Would Rush Do? - but then again, Dream Theater have almost made a career doing that. So, you're basically saying DT is a highly functioning cover band? That's not exactly something to celebrate in a band.
I disagree about the production - I think it's quite good.
The one where I agree the most is Mike Mangini's performance. When I saw TA live, I was simply blown away by him. However, on the record it does sound a bit stiff. Sections where he should be pushing the energy, like in A New Beginning, he plays a very staid, stiff, beat. I wish he'd play more like he did in Annihilator or Extreme rather than how he seems to prefer in DT. But his live performance was marvellous, and if DT release a Blu Ray of it, I will be more than satisfied, because I love The Astonishing, flaws and all.
Well, you just pointed out the main flaws of TA, something I have tried to describe myself but without using the appropriate words.
Some people do say that there are many melodies but yes many of them are boring and also repeated a bit too much. It's like watching the Titanic movie and hearing the same song or feeling you hear the same song too much.
There are some good songs in there, for me, just a few, a handfull. I mean, how are we suppose to rate TA? If I listen to the many ballads of TA and for example I compare them with a song like Wither, well there ain't any ballads of TA better than Wither. So I kind of rate them just average for most of them.
The drums: my biggest complaint is the sound. It really sound like a drum machine, especially the bass drum. And about the feeling, I really mist Portnoy who was the first drummer reminding me some of the best recordings of Rush's Neil Peart. Mangini is a great drummer. On the ADTOE tour, he just delivered the best drum solo I had seen. And I know that skills wise, he's on top.
Musically, the skills level on TA appears to be one of the lowest level heard from all the band studio records.
No epic songs on TA but that's ok. It is not a must but for me it's just that too many songs are average.
And me too, I love Our new world.
SFAM is their best album. Just the guitar solo on Home is in another league comparing that to TA .
