Are these sentences grammatically correct?

Here are three sentences from my last review and editor's comments on them. I have put them through three different writing and grammar aids. Except for the last one, I cannot find anything wrong with them. Any input would be greatly appreciated. Thanks.

1. Totally different and very original in concept. 
incomplete sentence
2. There was some romance and a few erotic scenes, but really doesn’t go into much detail. 
There was some - incorrect verb form (There 'were')
3. I have to say, I love the way this book ended. 
have to say, I love - comma splice

1. This is a sentence fragment. Writers everywhere are using them, but most OBC editors will not allow them.
2. I think your subject is "scenes," so you need a plural verb. The bit after the comma is a little odd too.
3. This is often okay in the outside world, but not here. I believe a colon would have been safe.

I hope this helps.

Thanks for your input Juliet. Much appreciated.

1. This sentence is incomplete, because it does not have a subject. (What is it that is totally different and original?)
2. The second part of this sentence ("but really doesn't go much into detail") does not have a subject and is therefore incomplete (Who or what does not go much into detail? Though you're evidently talking about the book/author, I believe that it's a good practice in English to always include the subject while writing).
3. This might be subjective, but I would have put it this way: "I have to say that[i/] I love how this book ended"

Hope this helps!

Your reply helped me too - thanks so much.
