This is not a debate, all personal opinion, but what did you find unbelievable?

-that he did not side with the deviate son who murdered his father and escaped?
-that he ended up a slave and gladiator?
-that the emperor had difficulties deciding to get rid of him?
-that the emperor decided to fight the Gladiator after fixing the match?
While it could be argued that in real life the emperor would have simply ordered him killed, that is neither here nor there, when it comes to being entertained.

I find this variation on the story within the realm of enjoyment and no problems at all with suspension of disbelief.
Em, may I respond by saying all of it, that is, that I find all of it simply unbelievable?
Now, there is no dispute historically that Marcus Aurelius ranks as one of the better (more enlightened, educated, philosophical, talented, etc.etc.) Roman Emperors, nor that his son was a capricious, dissolute, depraved, reprehensible individual with a curiously disagreeable capacity for cruelty, whose tenure as Emperor ended in outright megalomania (and, almost inevitably in a polity where such leaders can be difficult to overthrow, assassination). That is not in doubt.
Historically, yes, I have huge difficulty with numbers 2, 3, and four - they strike me as not really credible. Re No 1, the general in question could indeed have decided not to side with Commodus, but that would have led, most likely to his exile, and possibly murder.
While Commodus did indeed love public entertainments - and busily bankrupted the state treasury to pay for them, and also participated in rigged gladiatorial contests, this was an activity that scandalised Romans, especially the upper classes, rather than delighting them.
Moreover, while Commodus was indeed a thoroughly despicable creature, nothing I have read in a historical source (as opposed to movies, or fiction) suggests he murdered his father.....
However, each to his or her own. Here, I'll readily concede that I willingly suspend whatever disbelief I'd normally cultivate whenever a
Star Trek movie (preferably the better ones, of course), or the TV series
Star Trek TNG, or
DSN, are broadcast, or even at a push, this tolerance and affection, and enjoyment will be extended to some of the better episodes of the original ST.
And, as for
Downton Abbey, of course, I know full well it is utter tosh at times, but despite my background as an historian, I suspend every known critical faculty when watching it.......
"...Cabinet..." really displayed German cinematic expressionism to a larger audience than earlier efforts. And the 1922, F.W. Murnau "Nosferatu" was, imo, visually brilliant. Also the stories about the star, Max Schreck, never allowing anyone on the set ever to see him out of costume or character made it that much creepier. He was, apparently, a trifle strange!
Agreed. These are amazing movies for the era, a stunning example of the use of cinematography (lighting, atmosphere, and some very striking acting) to tell a multi-faceted and chilling story.
Scepticalscribe, I wasn't talking about Gladiator when I wrote "good movie all around". Words got mixed up a bit, since I referred to LA Confidental.
Vodoo Man, I've never heard about it. Is it wrth watching? I'm generally more into Karloff, but can appreciate a well made Lugosi 40s movie, of course. I really liked the
Black Cat and especially
Island of the Lost Souls (where he only played a minor role / cameo). And yeah, I was actually calculating the decades which must have accumulated into the 90s. But hard to tell how old he was back then when all you've seen are more or less lots of thick layers of make-up. I figured him minimum in his mid 30s in 1945 (thinking he must have been much older actually), that would have made him around 80 years old in the 90s...creepy stuff
About Nosferatu: I can heavily recommend the Eureka deluxe version with audio commentary. Very interesting (ok, admittedly for someone without any knowledge) stuff to learn about visual concepts or cinematography (i.e. the fast forward scene with the carriage when Hutton first enters into the realms of Nosferatu; and so forth).
Twietee: don't worry, I know perfectly well that you weren't talking about
Gladiator, but about
LA Confidential; instead, I was talking about
Gladiator, (and still seem to be doing so....)
