The narrative is all silly. Carpenter may not be a superstar, but he was one of the 5 or 10 best players in the National League this year. Petey, Ellsbury have bigger names certainly, but whose fault is that? Pedroia, Ellsbury and Victorino have all had MVP-ish seasons (at least getting votes). Superstar is a weird term to use for somebody as scruffy as Pedroia, but he is the Red Sox "brand name" player and a former MVP - most alleged superstars don't have that going for them.
These are two superb offensive units with a lot of diversity. The Cards are not as proficient with the homeruns, but they double plenty and their home park is not one that yields much of that anyway. Nobody is weeping for them, they led their league in runs and On Base too. After the Red Sox 1-year lapse in managerial/front office competence is back with Saint Louis as two of the best run orgs in the entire league - outfits which have spit out GMs for other teams as much as wins. The Sox beat some top shelf starters in the ALCS - the challenge in the World Series harkens back more to the Tampa series ... a pitching staff with youth and stuff for days.
Now I don't want to get too bogged down in the analysis - after all, this is baseball and if four pitchers throw four shutouts, all of this analysis goes out the window. (it's like having a hot goaltender in hockey in that sense) But the Red Sox will bring their batting eye with them and force the Cardinals pitchers to come to them. This postseason it has resulted in some big innings, yes - but it also has allowed them to create opportunities when they weren't hitting. (it is rare to say a near no-hitter with 17 Ks featured some GENUINE squanders, but the Red Sox had em in Game 1 of the ALCS) LOBs suck, but it is the stat that is not all bad - since it means that you are generating chances.
Key player in the series is Allen Craig who can close the gap between the lineups substantially if he is healthy. For Boston, it's still the starting pitchers. If they can continue to allow Farrell (his own compulsions aside) to be able to skip the Morales-Workman part of the bullpen every time out, we're going to be in good shape.
