Hi there, I always think it's worth trying to revive a neglected starter, as long as your not seeing any mold or bad bacterial growth. The first feeding you'll probably have to add extra liquid to get it to be the correct consistency, but I'm guessing after 3 or 4 days of twice a day feedings at room temperature you may well see some good activity. The tricky part is determining if you're actually reviving your starter or creating a new one from scratch, since the feeding process is similar, and you're likely to see activity after a few days in both cases. Look to see that your starter is rising and falling consistently within a 12 hour period and has a slightly tangy aroma to determine if your starter is mature and ready to use in your baking. A revived starter will usually only take 3 or 4 days to return to normal activity, while a starter that is created from scratch can take around 10 days to reach maturity.
