well....I'm not against a little intrigue or mystery. If those elements keep you interested in the story and characters....then that is fine.
But, if it's so vague and open to interpretation.......then it can create confusion.....especially when it relates to a character's powers / abilities ( Superman's vulnerability to Kryptonite ) or if a movie is based on previous movies.......
In the case of the X-movies......there were no previous movies to be based upon.....Xavier's mysterious past and relations to the other characters was not dealt upon previously.....so that creates intrigue and makes the viewers curious......
It would be like a director, 10 / 20 years from now, deciding to do another X-men movie that continues Singer's vision, and ignores X3. But, if that movie is not a direct sequel to the events of X2, and is instead a "vague sequel" to X1 and X2 that is related somehow to those movies.....then that can create confusion.
Especially when the director starts changing the relationships around. Says, having Cyclops and Jean be married. Then, the audience has to compare that to their relationship in X1 and X2, and try to figure out how this new movie fits in.
And, that's what happened in SR. In SR, Supes and Lois obviously had a prior relationship, had sex, and then Supes left abruptly without saying goodbye to Lois. Also, it appears that Lois doesn't know Supes is Clark. Plus, it establishes that Supes and Lex had a prior showdown....which landed Lex in jail.
But, how does that fit into Superman 1 and 2 ( which SR is supposed to be vaguely based on )? In Superman 1, Lois died, and Supes turned back time ( disobeying Jor-El's command ) to save the woman he loves. Is that the same Superman who would sleep with Lois and then leave abruptly without a goodbye?
In Superman 2, Lois found out Superman's identity, Supes gave up his power, slept with Lois, got his powers back, then Amnesia kissed Lois. Does SR include all that into its continuity?
When did Supes and Lois sleep together? Did they do it ala Superman 2? Or, as SR seems to suggest, did they do it after the "First Flight" night in Superman 1? However, in Superman 1, that "First Flight" nigh scene is a very innocent one and never implies that they hopped into the sack afterwards.
Same with Lex. Was Lex in jail because of the events in Superman 1? Or was it after the events in Superman 2?
SR leaves all these questions open......because it ( or Singer ) never clearly delineates how SR fits in......and that's confusing.....especially to ppl who are NOT familiar with the older movies.
