Another Noah fan? You have taste, good sir.
That said, as someone who played Andromeda to completion (as in, to the end of the game, not doing literally every activity, though I did get every planet 100% inhabitable), the stuff I'm reading here is the same sentiment I had. Andromeda, to me, is just boring. The characters are boring, the planets are boring, the enemies are boring, the exploration is boring, the combat is...actually, the combat's pretty neat. It's the one thing Andromeda does quite well, even if, as an RPG, I was so maxed out by the end there was no challenge or tension.
On the subject of theme, I've heard people say Andromeda is a critique of colonialism, while others have said it's an endorsement, but IMO, neither of these things are really accurate. I mean, there's the fact that the Andromeda Initiative isn't native to Andromeda, but this is never really an issue. There's a group of angara that resent the Initiative, due to the angarans' bad experience with the kett, but none of this is particuarly compelling. Wider angaran society accepts the Initiative pretty quickly, the angarans are a 'good' race (bar those extremists), while the kett are unironically evil, who do evil things, and talk evilly, and even get to look evil. Trying to pin Andromeda as reflecting colonialism at all doesn't really work IMO, because everything's black and white. Angarans are good, we help the angarans, we fight against the kett, who are the bad guys, we beat the kett, all the worlds in Heleus are now inhbaitable, everyone lives happily ever after until the sequel that's never going to happen.
I know I've come off talking about XC2's supposed depths that may or may not actually be there, but to me, Andromeda has the thematic depth of a puddle. Even the original Mass Effect had some thematic emphasis in regards to how humans might interact with alien species, and mostly pushing forward the idea that we're at our best when we work together and differences are celebrated, but Andromeda doesn't even manage that.
