Yeah, Troops is better than Tietanic. But it has its merrits! Best part of course being "Bloody Row faste- Sprlhplfff" And the guys head exlpodes. See, Troops was original and witty! And it looked really good! It had that Cops feel! Tietanic, although being hilarious, still has that "amateur" feel to it.
Though for the more Amateur Fan film parodies, I do Suggest either "Death Star Repairmen" or "Pink 5".
DSR doesen't have that good dialogue, but it has some funny antics. Pink 5 on the other hand is funny, cause you can't really go wrong when you have a ditzy blonde flying an X-wing for her first time and heading over to the Death Star, while taking calls from Han Solo. Thogh it stretches, it still quite funny.
