I enjoy watching this show. The drama is good. Watching people connect is interesting. However I do not think Exes should appear on the same show because if you didn't find love in real life settings you shouldn't find it in a romantic place with an ex. When you get back to life the problem is there!
Contestants also should not use people to get a vacation on tv.
Example: Brendon,Piper and Natasha. Using Natasha to stay till Piper came is WRONG!
