I think that how Saren was able to have even that moment of free will at the end of ME1 tells very much what kind of individuals Spectres are. Among other things, those who get chosen to be a Spectre has extremely strong will. They are no ordinary people.
I have couple of other theories in addition to strong will of Shepard why she/he is able to resist indoctrination.
Perhaps the Prothean beacon was able to "program" Shepard with some sort of resistance (it was able to program Prothean language in Shepard's brain) against indoctrination.
Then, in ME2 Shepard is pretty much a cyborg and perhaps indoctrination isn't as effective against synthetic, or augmented beings as pure organic beings. Sovereign weren't completely successful with the Geth for example, though there was entire collective Geth processing power against just one Reaper's processing power. It would be nice to know more about this...
One more theory I can think of is that Reapers don't want really indoctrinate Shepard (yet). Perhaps they want to know how Shepard, who is "becoming annoyance" for them (to quote Harbinger) is able to do such things. Perhaps Reapers can't get all the information they want from indoctrinated person, but want to capture and study Shepard to analyze this annoying unseen variable in their plan.
To sum things up: For me some sort of combination of these theories would make Shepard's resistance for indoctrination believable.
1. Very exceptional, extremely strong willed individual right from the start slows down indoctrination process (without destroying the subject).
2. Prothean counter measures Shepard gained from Prothean beacon. Could be something simple, like altering how Shepard
perceives ultra- and infrasonic waves and so damping at least psychological effect, for example.
3. Shepard is a cyborg, not entirely organic or synthetic, making indoctrination process more complicated and slow.
4. Reapers would rather study than indoctrinate Shepard. Reapers know from previous cycles that person like Shepard would destroy him/herself as soon as he / she would start feeling symptoms of indoctrination. So Reapers would lose valuable subject to study.
Also, quick indoctrination (just bake in 15 Mhz frequency at 180 dB for two hours and add some
water uh, EMP) might destroy what is valuable in Shepard to study.
