Yeah Castle is still holding my attention too. Bones and the Mentalist all fell by the wayside a good time ago.
Might have a look at Scorpion. thanks for that.
The mentalist ended about 2 weeks ago. Spoiler: jane and Lisbon get married
Scorpion is decent . It also getting good ratings so id see it holding out at least 5 seasons
The blacklist over on nbc is also good
