I once tried to start with the first season of the Real Housewives of Miami and unfortunately didn't stick with it.
Now I've started with the “new” episodes, so season 4 and ... hell, I love it! The drama is completely different to what we know from Beverly Hills or Salt Lake City. I love Alexia and her storylines!
I'll keep watching Season 5 an 6, but think I won't make step back to season 1-3.
