This "part 2" is neither a sequel or a prequel. It's a completely different reinterpretation with a different focus. It didn't even mention the "Bible Code" that was the basis for "part 1". Without checking the cast list, the only one that was in "part 1" was the anti-christ Stone Alexander.
It also lacked emotional impact. The scenes, you'll just have a logical reaction to it, "oh, that was bad", "ahh, humanity is easily tricked", and so on. For example, during the Megiddo war, there were scenes shown where a soldier's leg was blown, but it lacked emotional impact. They spent minutes upon minutes showing scenes of the war, soldiers dying, humanity divided between good and evil, but it all lacked any emotional impact. It was totally like watching a slide while listening to someone do their presentation. The idea (logic) is there. What they want to portray. But that's about it. In literature fiction, they didn't follow the golden rule: show don't tell.
If anything, stick to "part 1", it's more than enough. And if you are truly curious about the eschatology (the study of end-times), for whatever reason, dive into it directly, you'll get a more complete overall picture of what could be.
