I generally agree. While eezo and mass effect physics may be completely fictitious (although I believe the latter actually is inspired to a degree by real science), in general Mass Effect has attempted an unusual degree of scientific hardness and internal consistency for a space opera franchise. Even the pseudo-Lovecraftian Reaper technology has had some amount of its workings explained as the series went on.

As a result, at least to me, the sudden appearance of the Crucible and its "clarketech" capabilities, while perhaps not out of place in something like Star Trek, comes across as very jarring with this particular background.

In fact, I think I've said before that I appreciated Leviathan not just for reinforcing more thematic elements of the ending, but also for, with Leviathan technology, showing more of this kind of barely-explained supertech weirdness - it makes the Crucible a bit less obviously out-of-place.

Also, The Milkman - leaving out the debate aspect of it, the term you are looking for is deus ex machina, as in Deus Ex. Not "dues".
