Hi,
I used Rosetta Stone when I started Japanese, Korean, Russian and Swedish, so I have quite a bit of experience with it.
I completely agree that in the earlier stages it is pretty useless, and what I dislike about it is that it doesn't teach grammar properly and that it is so repetitive that you get bored very quickly.
This aside though, I have found it quite useful, though using it in conjunction with other resources (which you've said you're doing) is a must. Rosetta Stone covers A LOT of vocab without you realizing it, and it genuinely does help with language learning.
Later on the lessons are more complicated, and you cover more than just "the boy is eating", so I would recommend sticking with it.
As far as other resources go, I was going to suggest Duolingo, Babbel and Memrise, but that's already been done!! Those three are really good so check them out. Other things like watching subtitled French films, listening to French music etc. would be good at exposing you to spoken French, so is suggest that too.
Good luck
