...But it was a great show. Gale fucking like beast in the beginning. The Canadian party (Emmett in plaid should be made criminal!). Dr. Dave's possessiveness really came out finally (I mean, really, change flight arrangments without even a "mother, may I"? Bad manners, Dr., very bad manners). The prom scene was very sweet (although a bit sugary for my tastes).
1. So noun+ ving +noun ---->can used as a sentence, as noun, as individual, without following by clause or modifying some word?
2. Is it participle phrase or gerund phrase?
3. Is it the same case as "Michael and David disagree about Michael puttting up his posters"?
Not really; I'd change the punctuation:
But it was a great show: Gale fucking like a beast at the beginning.
