i agree with the whole new power lvls that go unexplained.
my real problm really started with DC comics on that point.. i enjoyed the comics in the 80's and 90's but, after a while mid 90's i started to notice a competition between DC character powers and marvel's character powers. it became petty and dishonest and it seemed to originate more from DC then marvel and also was extremely mean spirited at times.
i mean if a marvel character did something then a few months later a DC story where a character did the same and surpassed even though DC made it inexplicably clear at the time no more asinine feats b/c of the inconsistencies they caused and b/c it would undo their company sponsored retcons where characters were put back at a moderate lvl of power.
example:
Sue and thor contain a nuclear blast soon a green lantern kyle contains a nuclear bomb although ambient struggling.. the caption clearly shows and states that it takes all his concentration and will to pull such a feat also the ring reaching its power limit.. but it seems to tail marvel feats not really bothered by it. but, a few yrs later the nuke feat isn't enough now you have him containing supernova lvl energies and the ring no longer seems to possess its energy limit it once had.
superman on panel takes a blast and scientist comment how the blast can shatter adamantium easily and superman isnt even bothered by it.. hmm.. did a rival company really need to make such a statement, now ppl try to use that as an argument for battles?
another is superman stops a prison riot where suspiciously many of the criminals seem to resemble marvel heroes. superman flies in and single handedly stops them all including the abstract cosmic ones all while making fun of the characters and how weak they really are through slapstick..
it comes down to DC never being able to stay consistent nor respect the retcons that were put in for a reason to stop the foolishness of altering origins and powers.,
it would be like if marvel did and operated the way DC does captain america would have had genetic altering in a flash back and instead of drinking the serum he was injected and operated ultimate style. fans would be up in arms.... if that isnt enough if a writer said that it was red skull who was actually his father.. ppl would be screaming to have the writer fired and marvel be tying hard to change back the story or find a way to dismiss it as non canon..
