This trailer shows a lot of dialogue scenes and is good because there is only two main actors in it so it would be easy to arrange a time to shoot. I also like the fact it tells a story throughout the trailer without really giving away the big story lines which is what a trailer is designed for.
These trailers are all quite realistic and don't feature a lot of special effects in them which means it would be good for us to produce something of this genre (Comedy/RomCom) as they don't often have a lot of effects which we couldn't reproduce. These feature quite a few of dialogue scenes which we would include to show some of the storyline without giving out major plot lines.
