I wouldn’t like to see more. I had stopped after two, but decided to watch them all recently. The first is amazing. Two is fine, but starts getting weird. For a franchise that succeeded because of its realistic portrayal of firearm usage, the magic really starts ramping up here. Three and four are strange considering where the series started. They’re alright action flicks I guess, but I didn’t really care for them. I don’t see any need for more.
