I first got introduced to Leverage through Hustle, the UK equivalent of Leverage but less technologically-dependent.
I just finished all 5 seasons of Leverage and I must say it is a pretty good show with a good storyline that does not digress to intercharacter relationships *hint* TBBT *hint*
I hope that show gets a new season... It is a change from the other melodramatic US shows that do not stay align to their themes. The Mentalist is not bad but I got bored of it after a while lol.
