Pretty easy to find the groups but nice grid all the same. Thought the suicide squad group should have accepted Batman as a connection.

No red herrings that I could see?

Wouldn't accept TBBT, but that's certainly more of an indictment on my laziness than the setter's rigour ;) Aslo, glad "Charlie" was accepted in lieu of "Willy Wonka" as I prefer my childhood memories to remain in the literary rather than cinematic sense...

This is fun and it really makes you think.
