Yes, I am inclined to think that life on earth is unique in that life on extra solar planets is not likely to be anything like what we are familiar with. On the other hand, I do think it is possible that if life is discovered on other planets in our own solar system (or other moons of those planets), it may indeed turn out to be relatively similar at least on the microbial scale. This may be a consequence of an increasingly popular theory that the "seeds" of life here on Earth may have come from asteroids, comets, and/or other Kuiper belt objects, etc., and thus similar seeds of life were sown elsewhere in our solar system and may have at least a common origin or starting point. I think that all bets are off though as far as lifeforms higher than microbes are concerned.
