The question is not whether to crew or not to crew. It’s whether you always want more of a good thing 
And the second bite is even better as more spices reveal themselves…
I have now seen the review and if you just have a look at all the different new cards you may have to fulfill those are just so much fun… if you enjoyed the first, you are going to love the second. But I am with Tom that if you have not played trick tacking games before you may want to start at the first. If you didn’t like the first: you won’t like the second one either. If you are sick of the first, the second may provide welcome enrichment of the system or you may still be sick of the first having played, too much…
I disagree with Tom about one thing: even in the original game sometimes you stumble into situations that are impossible to solve from the first trick. It does happen more often in Deep Sea.
