How good are the other seasons ?

I just finished the first season and I liked it, the strongest point for me was how interesting of a character Lorne and Lester ( later on ).

I felt some episodes had really bad parts where for like 15 minutes nothing relevant would happen. I still enjoyed it but since season 2 and 3 are complete different stories with different characters I don’t know if I will like it.

Compared to season 1 how good are the characters and the setting ? Is there any odd character like Lorne that even though he is bad still makes you root for him ?

This is what you want
