As film sessions go, it was only slightly less horrifying than “The Human Centipede” or “House of 1,000 Corpses.”

Monday at Gillette Stadium, the Patriots got their first look at the film of their Sunday loss to the Jets. And while the first half was a mostly pleasant montage of ball control and complimentary football punctuated by a pair of Tom Brady touchdown passes, the second half was a nightmare of defensive breakdowns, turnovers and plenty of ill-timed penalties.

Set against a gruesome the backdrop of Fireman Ed and a collection of crazies yowling into the night at the new Meadowlands Stadium, it was strictly NC-17 fare for the Patriots.

“After watching the tape [and] going through the game, there’re obviously a lot of things we need to do better,” Patriots coach Bill Belichick said Monday. “So we’ve just got to get back to work this week and get ready for Buffalo and also get things straightened out on our end — just things we need to do better.

“It’s pretty much across the board and all three phases of the game: playing, coaching, offense, defense, special teams, you name it. It’s just not as efficient as what it needs to be.”

Offensively in the second half, the Patriots couldn’t score. They had 80 total yards of offense and ran the ball just six times for 20 yards, while Brady was 7-of-16 passes for 69 yards, no touchdown passes and three turnovers — two interceptions and a fumble on a sack.

While Brady said Monday there were some “encouraging” signs for the offense, he added the inconsistencies displayed by the New England offense in the second half of Sunday’s game left him “frustrated,” especially when it came to playing complementary football.

“We couldn’t complete passes and we couldn’t run the ball. So, we couldn’t convert on third down to stay on the field … and then the turnovers,” Brady told WEEI Monday morning when asked about the difference between the first and second halves against the Jets. “We just couldn’t make enough plays in the run game or the passing game to stay on the field consistently.

“We really hung our defense out to dry when they’re out there trying to stop them, and we’re giving them the ball back and they have to go back on the field. It wasn’t very complementary of us in the second half, and we just couldn’t stop the momentum. The Jets had it, and we really couldn’t stop them from continuing to move forward, and we couldn’t do anything offensively to get it back on our side.”

On the other side of the ball, New York quarterback Mark Sanchez completed a career-high 21 passes on 30 attempts for 220 yards and three touchdowns (two in the second half), his best game as a pro. Tight end Dustin Keller continued his career as a Patriots-killer, catching seven passes for 115 yards and a touchdown. And veteran running back LaDainian Tomlinson rushed for 6.9 yards per carry and 76 yards, helping the Jets put together second-half scoring drives of six, eight and ten plays.

“We had some opportunities out there to make the plays, and we just didn’t make the plays,” nose tackle Vince Wilfork told WEEI on Monday. “It wasn’t anything they were doing that we didn’t expect they were going to do. We didn’t make the plays when we needed to. When we needed plays, it was like we were searching for someone else to make it instead of taking upon [ourselves] and going out there and getting it.”

Second-half breakdowns on the road are nothing new for the Patriots. In 2009, problems in the third and fourth quarters on both sides of the ball resulted in late losses against the Colts, Broncos, Dolphins and Jets, four games where New England led at halftime. On Sunday against New York, it was more of the same.

Not including last year’s trip to London to face the Bucs — which was a neutral site — the Patriots have been outscored 116-41 in the second half over their past eight road games.

While no one was quite able to put their finger on the reason for the second-half swoons away from home, Brady said after Sunday’s game a lot of it is on his shoulders.

“I think when it comes down to these second-half games and our level of toughness, we've got to go out there and play tougher,” said Brady of the Patriots, who have now lost seven of their last nine away from home. “I have to do a better job of leading this team and certainly execute better when it’s crunch time.”

The Patriots figure to get something of a reprieve this week against the Bills. First, it’s a home game, and second, a woeful Buffalo team has struggled to put together much of anything on either side of the ball through the first two games. The Bills have 19 points through two games, and Buffalo coach Chan Gailey announced Monday that former Harvard product Ryan Fitzpatrick would take over at quarterback for Trent Edwards.

Just the thing for a team looking to put an ugly finish behind them.

“First thing we have to do is put that game behind [us]. We have to have a short memory,” said wide receiver Julian Edelman. “That’s what we have to preach to our guys right now, and that’s what we’re doing. We have to take from that film we just watched. Take all the bad things and learn from them, fix them and go out here next week and prepare for the Bills and get better.”
