Loved it.
I must admit I've been looking forward to this and was so pleased to see it was a crossover with Castle.
Loved your banter between Castle and Beckett, it was spot on and I could hear their voices in my head.
Now, all I want to see is the turnaround in 2013 when Lois and Clark call on their friends Castle and Beckett ... because I'm convinced that they will have recognised them once they became friends some time in the future. Lois and Clark are also pretty intelligent and have had experience of time travel. They will figure it all out and are just waiting for that time when they go to visit and Castle and Beckett act just that bit differently!!!!
Pretty please. *tries to look like a cute little girl that cannot be resisted*
